For the trigonometric and hyperbolic functions, we show that Pythagorean triples can lead to such tables in little time and memory usage. When targeting correct rounding in double precision for the ...

Mastering degree-radian conversions is crucial for trigonometry and calculus. Radians simplify mathematical formulas, ...

Chapter 4 (Investigating Trigonometric Functions) treats the trigonometric functions graphically and analyzes the meaning of graphs, also with help of their derivatives.

These identities are particularly useful because they allow you to express any trigonometric function in terms of sine and cosine – often the key to solving complex problems.

Nowadays, problems such as greenhouse effect and air pollution become increasingly prominent. The power generation process should pay attention to the fuel cost and reduce the pollution to the ...
