Find the derivative of the function. f(t) = tan(e^9t) + e^(tan 9t)
|dw:1362233655486:dw|
|dw:1362233696126:dw| Here is my work, where did I make an error? please help I'll give a medal in return. Really need the help, thanks
\[d/dt(\tan (e ^{9t}))\]=\[\sec ^{2}(e ^{9t}).e ^{9t}.(9)\]
would you happen to be familiar with WebAssign?
my answer comes out incorrect in webassign
Should be \[\frac{d}{t d}\text{}\tan e^{9 t}+e^{\tan (9 t)}=9 \left(e^{9 t} \left( \sec ^2e^{9 t}\right)+e^{ \tan(9 t) } \left( \sec ^2(9 t)\right)\right)\]
