How do you simplify {eq}\displaystyle \rm tan \ 4 \theta {/eq} to trigonometric functions of a unit {eq}\theta {/eq}?Double Angle Identity for Tangent Function:Double angle identities relates the trigonomteric functions of an angle {eq}2u {/eq} with the trigonometric fu...
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.
In order to prove any trigonometric identity equations, we must know the various trigonometric identity formulae. The proof needs just the manipulations and rearrangement in various forms. The following identities will be sufficient to prove this one: 1+cos2θ=2cos2θ1−cos2θ=2...
