Answer

$y'=x^{sinx}(\frac{sinx}{x}+lnx cosx)$

Work Step by Step

Given: $y =x^{sinx}$ Taking logarithmic on both sides of the function $y =x^{sin x}$ $lny=sinx .lnx$ Take implicit differentiation with respect to $x$. Apply product rule of differentiation. $\frac{d}{dx}(lny)=\frac{d}{dx}(sinx. lnx)$ $\frac{1}{y}\frac{d}{dx}(y)=sinx\frac{d}{dx}(lnx)+lnx\frac{d}{dx}(sinx)$ $\frac{d}{dx}(y)=y[sin\times(\frac{1}{x})+lnx(cosx)]$ Hence, $y'=x^{sinx}(\frac{sinx}{x}+lnx cosx)$
