Pythagorean identities Trigonometric functions and their reciprocals on the unit circle All of the right angled triangles are similar i e the ratios between their corresponding sides are the same For sin cos and tan the unit length radius The two formulas of sin squared x are i sin 2x 1 cos 2x and ii sin 2x 1 cos 2x 2
Sin squared double angle formula gives the trigonometric formulas for the expressions sin 2 2x To express the sin 2 2x formula we just replace with 2x in the sin 2 formula So first let us write sin 2 formula sin 2 1 cos As many people have pointed out by now sin 2 x is simply a nickname for sin x 2 Therefore sin 2 30 sin 30 2 1 2 2 1 4 As it happens though there is another
