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.

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) WebStep 1: Enter the function you want to find the derivative of in the editor.

WebAug 10, 2024 · f' (x)= e^ x : this proves that the derivative (general slope formula) of f (x)= e^x is e^x, which is the function itself. In other words, for every point on the graph of f (x)=e^x, the slope of the tangent is equal to the y-value of tangent point. So if y= 2, slope … WebNov 2, 2015 · Calculus Differentiating Trigonometric Functions Derivative Rules for y=cos (x) and y=tan (x) 1 Answer Jim H Nov 2, 2015 f '(x) = cosx Explanation: This is a trick or trap question. The long and tedious way to this in by the product rule, then simplify. The quicker way is to observe that f (x) = tanxcosx = sinx cosx cosx = sinx. So, f '(x) = cosx.
