Summation Formula: A closed-form expression used to compute the sum of sequences, particularly those involving trigonometric functions, without recourse to term-by-term addition.

Trigonometry Table is a table that helps us to calculate the values of trigonometric ratios for common angles such as 0°, 30°, 45°, 60°, and 90°. But it is difficult to memorise the values.

Each trigonometric function also has an inverse that can be used to find an angle from a ratio of sides. The inverses of sin (x), cos (x), and tan (x), are arcsin (x), arccos (x) and arctan (x ...

Mastering degree-radian conversions is crucial for trigonometry and calculus. Radians simplify mathematical formulas, especially in calculus where trigonometric function derivatives rely on radian ...

Learn how to solve trigonometric equations in Higher Maths involving multiple or compound angles and the wave function in degrees or radians.
