The six trigonometric functions are sine, cosine, secant, cosecant, tangent and cotangent. By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin ฮธ = Opposite Side/Hypotenuse. cos ฮธ = Adjacent Side/Hypotenuse. tan ฮธ = Opposite Side/Adjacent Side.

The Law of Sines The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C It works for any triangle: And it says that: When we divide side a by the sine of angle A it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C Sure. ?

Proving Trigonometric Identities - Basic. Trigonometric identities are equalities involving trigonometric functions. An example of a trigonometric identity is. \sin^2 \theta + \cos^2 \theta = 1. sin2 ฮธ+cos2 ฮธ = 1. In order to prove trigonometric identities, we generally use other known identities such as Pythagorean identities.

The following (particularly the first of the three below) are called "Pythagorean" identities. sin 2 ( t) + cos 2 ( t) = 1. tan 2 ( t) + 1 = sec 2 ( t) 1 + cot 2 ( t) = csc 2 ( t) Advertisement. Note that the three identities above all involve squaring and the number 1. You can see the Pythagorean-Thereom relationship clearly if you consider.
