Cos2x is one of the important trigonometric identities used in trigonometry to find the value of the cosine trigonometric function for double angles. It is also called a double angle identity of the cosine function. The identity of cos2x helps in representing the cosine of a compound angle 2x in terms of sine and cosine trigonometric functions, in terms of …

WebbAnswer (1 of 15): You are probably aware of the classic trig identity \cos^{2}x+\sin^{2}x=1 which we can write as \cos^{2}x=1-\sin^{2}x=(1+\sin x)(1-\sin x) From this we can find 1+\sin x 1+\sin x = \frac{\cos^{2}x}{1-\sin x} \tag 1 Equation (1) is a “formula” for 1+\sin x but certainly not... WebbIntegration of sin2x means finding the integral of the function sin2x. Integral of sin2x can be written as ∫ sin2x dx. Here, we need to find the indefinite integral of sin2x. So, the integration of sin2x results in a new function with arbitrary constant C. Let’s learn the formula for the integration of sin2x along with the derivation.
