Prove the following identity (sin (2x))(1-cos (2x))= 1(tan (x)) (sin (2x))(1-cos (2x)
The double angle formula is used to calculate sin 2x, cos 2x, tan 2x, for any given angle 'x'. The sine double angle formula for an angle 'x' is sin 2x = 2sin(x)cos(x).What is the Double Angle Formula? The double angle formula can find the value of twice an angle under sine...
