WebThe derivative of sin function with respect to a variable is equal to cosine. If x represents a variable, then the sine function is written as sin x. Therefore, the differentiation of the sin x with respect to x is equal to cos … WebMay 30, 2015 · 1 Answer. Using the quotient rule, the answer is d dx ( sin(x) x) = xcos(x) − sin(x) x2. While this is technically only true for x ≠ 0, an interesting thing about this example is that its discontinuity and lack of differentiability at x = 0 can be "removed". Let f (x) = sin(x) x. Use your calculator to graph this over some window near x = 0.
