Tan theta is one of the trigonometric ratios which is equal to opposite / Adjacent in a triangle. Practice a few questions based on the formula for tan theta at BYJU'S.
What is the double angle formula of tangent function? The double angle formula is used to calculate sin 2y, cos 2y, tan 2y, for any given angle 'y'. The tangent double angle formula states that for an angle 'y', tan 2y = 2 tan y/{1-tan^(2) y}. What is sin 2x double angl...
Common trigonometric functions have periods that are multiples of π; for example, sine and cosine have period 2π, so for any angle θ and any integer k, displaystylesintheta=sinleft(theta+2pi kright)textandcostheta=cosleft(theta+2pi kright). Many of the appearances of π in the ...
