Definition: A trigonometry function is defined as a function with an angle. The angle is often called (theta noted ” x “) or ( phi noted ” φ “). Also, You should note that the angles can be determined in Degrees(example: 300, 900) or in Radians(example: π/2 rad, π/3 rad).
Solving trigonometry functions can be easy and straightforward only if you know your 6 main trig functions!
