WebAug 4, 2015 · Use logarithmic differentiation: let y = xtan(x) so that ln(y) = ln(xtan(x)) = tan(x)ln(x). Now differentiate both sides with respect to x, keeping in mind that y is a function of x and using the Chain Rule and Product Rule: 1 y ⋅ dy dx = sec2(x)ln(x) + tan(x) x Hence, dy dx = y ⋅ (ln(x)sec2(x) + tan(x) x) = xtan(x)(ln(x)sec2(x) + tan(x) x)

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). WebxTAx= Xn i=1 xiail+ ˜a T lx=a Tx+ ˜aTx. In the end, we see that ∇xx TAx=Ax+ATx. 4 Derivative in a trace Recall (as inOld and New Matrix Algebra Useful for Statistics) that we can define the differential of a functionf(x) to be the part off(x+dx)− f(x) that is linear indx, i.e. is a constant times dx.
