WebJan 7, 2024 · d dx (sinxcosx) = cos2x Explanation: The product rule can be used to differentiate any function of the form f (x) = g(x)h(x). It states that f '(x) = g'(x)h(x) +g(x)h'(x). The derivative of sinx is cosx and the derivative of cosx is −sinx. f '(x) = cosx(cosx) + sinx( − sinx) f '(x) = cos2x −sin2x Use the identity cos2x = cos2x −sin2x: WebFigure 13 compares f ( x) = sin ( x) with f ( x) = sin ( x) + 2, which is shifted 2 units up on a graph. Figure 13 Variations of Sine and Cosine Functions Given an equation in the form f ( x) = A sin ( B x − C) + D or f ( x) = A cos ( B x − C) + D, C B is the phase shift and D is the vertical shift.

WebAug 9, 2016 · You can obtain sin(f(x)) as the imaginary part of eg ( x) where g(x) = if(x). So one might as well consider eg ( x) instead, which should be a bit simpler.
