WebSep 7, 2024 · Find the derivative of f(x) = cscx + xtanx. Solution To find this derivative, we must use both the sum rule and the product rule. Using the sum rule, we find f′ (x) = d dx(cscx) + d dx(xtanx). In the first term, d dx(cscx) = − cscxcotx, and by applying the product rule to the second term we obtain d dx(xtanx) = (1)(tanx) + (sec2x)(x). WebAug 1, 2024 · Multiply the number by the value of the exponent.
