tan 2y = 2 tan y/{1-tan^(2) y}. What is sin 2x double angle? 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...
sin x can be calculated using the product rule of differentiation. d(cos x. sin x)/dx = (cos x)' sin x + cos x (sin x)' = -sin x.sin x + cos x. cos x = cos2x - sin2x = cos 2x. Hence, the derivative of cos x.sin x = cos 2x What is the Second Derivative of ...
