A New Mathematical Work Introduces Original Trigonometric Graphs and Concepts
New Original Graphs in Trigonometry – Volume 1 presents innovative graph structures derived from fundamental trigonometric functions, offering fresh perspectives in mathematical visualization and analysis.
Manhattan, NY, New York, United States, 12th May 2026 – Author and mathematics researcher Chibamba Mulenga, Ph.D. announces the release of his new academic work, New Original Graphs in Trigonometry – Volume 1, now available to students, educators, and mathematics enthusiasts seeking deeper insights into trigonometric functions and their graphical behavior.

Developed through years of teaching and independent exploration, the book introduces a collection of newly formulated trigonometric graphs, many derived from transformations involving absolute values and function combinations. These graphs extend beyond traditional classroom material, offering readers an opportunity to explore previously undocumented patterns in trigonometry.
Rather than revisiting standard sine, cosine, and tangent graphs, the book focuses on original mathematical constructions, presenting them through structured definitions, examples, and graphical illustrations. The work contributes to mathematical learning by encouraging visual understanding and analytical thinking.
About the Book
In New Original Graphs in Trigonometry – Volume 1, Chibamba Mulenga explores how modifying classical trigonometric functions—such as applying absolute values or combining functions can lead to entirely new graphical behaviors.
One of the central discoveries discussed in the book is the function:
h(x) = sin|x|
Unlike the traditional sine function, this graph demonstrates symmetry about the y-axis, revealing a new perspective on trigonometric relationships. Building on this idea, the book expands into a wide range of related functions, including:
- Absolute value transformations of trigonometric functions
- Products and quotients of sine, cosine, tangent, and their reciprocals
- Composite trigonometric expressions and their graphical interpretations
The book combines analytical reasoning with visual representation, making it a valuable resource for understanding how mathematical transformations influence graph structures.
Themes That Matter to Readers Today
At its core, the book explores:
- Innovation within classical mathematics
- Visual learning through graph-based understanding
- The relationship between algebraic expressions and geometric representation
- The discovery of new mathematical patterns from existing functions
- The role of creativity and observation in mathematical advancement
The book is particularly suited for students, educators, mathematicians, and STEM learners, offering a fresh approach to trigonometry that goes beyond memorization and encourages conceptual thinking.

TheBuzzBlast Helps Etsy Sellers Build Brand Recognition Beyond The Marketplace
United States, 12th May 2026, Grand Newswire – Independent Etsy sellers facing rising fees and algorithm-driven visibility are turning to public relations firms to build name recognition that travels with them off the marketplace, where margins are higher and customer relationships are direct.
Rising seller fees and shifting search rankings on Etsy have pushed a growing number of makers to invest in off-platform brand visibility, according to public relations practitioners working with the segment. TheBuzzBlast, a public relations firm working with independent merchants, says coverage in craft, design and regional outlets is increasingly the lever sellers reach for when marketplace economics tighten.
The firm places stories with lifestyle, home, and hometown publications, where handmade and small-batch products tend to find editorial fit. Reporters covering those beats are looking for makers with a story behind the work, BuzzBlast notes, and Etsy sellers often have exactly that — without the time or contacts to surface it.
“A ceramicist in Vermont can have ten thousand Etsy sales and still be invisible the moment a customer closes the app,” said John, Chief Editor of BuzzBlast. “Press coverage gives makers an identity that follows them anywhere — to their own site, to a craft fair, to a wholesale buyer’s inbox.”
Earned coverage also functions as a hedge against platform dependency. Sellers who build name recognition through press can route customers to their own websites, sell at retail, or pitch wholesale buyers — moves that compound returns long after the original article runs.
The firm works on a project basis with sellers preparing for product launches, holiday seasons, or transitions to standalone storefronts.

Press Release
Designer Pool Covers Expands Across South Africa’s Major Cities
Designer Pool Covers has expanded its operations across Johannesburg, Durban, and Cape Town, reflecting growing demand for pool cover solutions linked to safety, water conservation, and residential design trends. The move aligns with broader shifts in South Africa’s home improvement sector, where functionality, sustainability, and aesthetics increasingly intersect.
Germiston, Gauteng, South Africa, 12th May 2026 – Designer Pool Covers, a South Africa-based company specializing in pool cover solutions, has announced an expansion of its operational footprint across key metropolitan regions, including Johannesburg, Durban, and Cape Town. The development reflects broader trends in residential infrastructure adaptation, water conservation awareness, and evolving safety standards within the country’s built environment.
The company, operating under the name “Designer Pool Covers,” has established its presence within the pool cover segment through a focus on design integration, functional performance, and compliance with safety considerations. Its expansion into multiple provinces marks a shift from a regionally focused operation to a more nationally distributed service model.
This development occurs against the backdrop of increasing attention to water usage and safety measures in South Africa, where residential pool ownership remains relatively high in urban and suburban areas. In regions such as Gauteng, KwaZulu-Natal, and the Western Cape, pools are a common residential feature, accompanied by ongoing concerns around evaporation, safety, and maintenance.
Designer Pool Covers’ expanded operations appear to respond to these factors by aligning product availability with regional demand patterns. In Johannesburg and the greater Gauteng area, demand is often linked to water conservation considerations and seasonal variability. In Durban, coastal conditions introduce factors such as humidity and debris accumulation, while in Cape Town, heightened awareness around water retention has influenced homeowner priorities.
Industry observations indicate that the pool cover sector has gradually evolved from purely functional offerings to solutions that also consider aesthetics and integration into outdoor design. This shift has influenced product development, with increasing attention to materials, usability, and compatibility with residential environments.
Designer Pool Covers’ portfolio reflects this evolution, incorporating a range of cover types designed for different use cases, including safety covers, thermal covers, and automated systems. These categories align with broader international trends in pool management and residential infrastructure.
From a regulatory standpoint, pool safety remains an important consideration in South Africa. Municipal guidance and safety recommendations emphasize the use of barriers and covers to reduce risk, with awareness continuing to grow among homeowners and insurers.
The company’s expansion into Durban and Cape Town introduces logistical considerations related to regional supply chains and service delivery. Coastal and inland environments present different performance requirements, influencing material selection and installation practices.
The move also reflects broader trends within South Africa’s home improvement sector, which has seen sustained activity driven by increased investment in residential spaces. Outdoor areas, including pools, have become central to these developments, shaping demand for complementary products.
Designer Pool Covers’ presence across multiple cities positions the company within a competitive and evolving market landscape. Companies operating in this sector continue to balance performance, durability, and cost considerations while adapting to regional and consumer-specific needs.
Sustainability remains a relevant factor, particularly in regions affected by water scarcity. Pool covers designed to reduce evaporation and heat loss may contribute to more efficient resource use, depending on application and maintenance practices.
As Designer Pool Covers establishes operations in Johannesburg, Durban, and Cape Town, its expansion reflects alignment with key economic centres and residential growth areas. Ongoing developments in safety standards, environmental considerations, and design preferences are expected to continue shaping the industry.
