\[\frac{ dy }{ dx }= \lim_{h \rightarrow 0} \frac{e ^{x+h} \sin(x+h)  e^{x} sinx}{h}\]

Maybe try an angle sum identity for sin(x+h), and for e^{x+h}, you add the exponents when multiplying powers of the same base. See if you can use that to factor things out.

i did the question till, \[\lim_{h \rightarrow 0}\frac{e^x e^h sinx \cosh + e^x e^h cosxsinh e^xsinx}{h}\] but i can't eliminate the terms
