Practise solving trigonometric equations in degrees or radians using CAST and its period to find other solutions within the range, including multiple or compound angles and the wave function.

The validity of standard singular integral solutions to classic dual trigonometric series equations is rigorously established in the case that the right-hand sides of the equations are functions of ...

Solve the equation \(5\cos (6x - 20)^\circ + 3 = 7.25\), for \(0 \le x \le 180\).

Trigonometry is the branch of mathematics that explains the relationship between sides and angles of a triangle. In a right angled triangle the three sides are perpendicular, base and hypotenuse, as ...
