Trigonometric sums and summation formulas have long served as essential tools for elucidating periodic phenomena across mathematics and the physical sciences. These techniques entail the explicit ...

Provides a review of pre-calculus algebra and trigonometry integrated with the first half of Calculus I: limits, continuity, derivatives, basic derivative formulas, chain rule, implicit ...

Formulas for differentiation are developed and include formulas for trigonometric, exponential, and logarithmic functions. Applications to physics, economics and geometry are highlighted. Successful ...

Double angle formulas are named so because they involve trigonometric functions of double angles, i.e., sin2θ, cos2θ and tan2θ. There are three main double angle formulas as below: where θ is ...

An understanding of the three trigonometric ratios and how to change the subject of a formula is essential. The Greek letter, Ɵ (theta) is often used as a symbol for an unknown angle. For a right ...
