   • Sine, Cosine, Tangent, Cotangent, Secant and Cosecant.
   • Sin A = Perpendicular/Hypotenuse Cos A = Base/Hypotenuse Tan A = Perpendicular/Base
   • Sin, Cos and Tan are three main functions in trigonometry.
   • The three fundamental identities are: 1. sin 2 A + cos 2 A = 1 2. 1+tan 2 A = sec 2 A 3. 1+cot 2 A = csc 2 A
   • Right-angled triangle
   • The trigonometric ratios tan equals cot when the angle equals 45 degrees. (i.e. tan 45° = cot 45° = 1)
   • Trigonometric formulas are used to evaluate the problem, which involves trigonometric functions such as sine, cosine, tangent, cotangent, cosecant...
   • The formula for sin 3x is 3sin x – 4sin 3 x.
