WebMay 26, 2024 · Explanation: dy dx [xx] = dy dx [exln(x)] Let u = xln(x) and thus, xx = eu. Apply chain rule: dy dx = dy d u ⋅ d u dx. = d d u[eu] ⋅ d dx [xln(x)] Derivative of eu is itself, Derivative of ln(x) is 1 x and also apply product rule d dx [f (x)g(x)] = f '(x)g(x) + g'(x)f (x) = (eu)[(x)( 1 x) +(1)(ln(x))] WebThe Derivative Calculator lets you calculate derivatives of functions online — for free!

WebAug 18, 2016 · Using the constant rule d/dx af (x) = a [d/dx f (x)] d/dx [8*3^x] = 8 [d/dx 3^x] So you don't differentiate 8 in this case. Had it been d/dx 8+3^x then you would use the sum rule, d/dx f (x) + g (x) = d/dx f (x) + d/dx g (x). d/dx 8 + 3^x = d/dx 8 + d/dx 3^x = 0 + ln (3) … WebThe derivative of x² at x=3 using the formal definition The derivative of x² at any point using the formal definition Finding tangent line equations using the formal definition of a limit Limit expression for the derivative of function (graphical) Practice Derivative as a limit Get 3 of 4 questions to level up!
