There are two ways we can find the derivative of x^x It's important to notice that this function is neither a power function of the form x^k nor an exponential function of the form b^x, so we can't use the differentiation formulas for either of these cases directly (i) Let y=x^x, and take logarithms of both sides of this equation ln(y)=ln(x^x)Differentiate the function y = (x^2 4x 3)/sqrt(x)The derivative of `y = (sqrt x x)/x^2` has to be determined Now for the function `y = (sqrt x x)/x^2` divide each term of the numerator by the denominator x^2

5 Derivative Of The Logarithmic Function
Inverse Functions Implicit differentiation can help us solve inverse functions The general pattern is Start with the inverse equation in explicit form Example y = sin −1 (x) Rewrite it in noninverse mode Example x = sin (y) Differentiate this function with respect to xThe slope of a line like 2x is 2, or 3x is 3 etc; 2 Take the natural logarithm of both sides You need to manipulate the function to help find a standard derivative in terms of the variable x {\displaystyle x} This begins by taking the natural logarithm of both sides, as follows ln y = ln a x {\displaystyle \ln y=\ln a^ {x}} 3 Eliminate the exponent
