It's not that much different in practice: you use u=1+sin(x)cos(x) while tan(x/2)=1−cos(x)sin(x). Both substitutions can be used for general ... (1-cos x)/sin x=tan⁡(x / 2) Hence, it can be concluded that the value of (1-cos x)/sin x is equal to tan (x/2). We have to find the derivative of . We will differentiate this expression with respect to x . Therefore, the given expression's derivative is − 1 1 − cos ⁡ x. Free Trial Available!
