Помогите срочно надо!!!!!!!

1) $y=tg(e^{x}) - sinx*lnx$
$y'= \frac{e^{x}}{ cos^{2}(e^{x}) } -cosx*lnx- \frac{sinx}{x}$
2) $y' = 5^{ \sqrt{x} }*ln( \sqrt{x} )* \frac{1}{2 \sqrt{x} } -(- \frac{2}{ \sqrt{1-4x^{2}} } )$ = $y' = 5^{ \sqrt{x} }*ln( \sqrt{x} )* \frac{1}{2 \sqrt{x} }+ \frac{2}{ \sqrt{1-4x^{2}} }$
3) y' = (1/e^(tg^2(x^4-3∛x)))*(e^(tg^2(x^4-3∛x)))*(2tg(x^4-3∛x))*(1/cos^2(x^4-3∛x))*(4x^3-x^(-2/3)) = (2tg(x^4-3∛x)*(4x^3-x^(-2/3))/(cos^2(x^4-3∛x))
