wanna get my answer checked please! Find an equation of the tangent line at x = 0 for the given function. y = 3e^x[sin(x)] i had 1 as my final answer.
is the [sinx] a part of e power?
no
ok
its just 3e to the power of x times sinx
if i got the question correctly... the answer is 0.
why
\[3e ^{x}sinx\]
yes... you want tan(0) by given function, right?
no .. i just want the tangent line, so i get the derivative of the function then i sub in 0 for x.
so i used the product rule and got 3e^x (cosx+sinx)
so when i subbed in zero i got 1.
ahhh... yes i think u did well... i didn't got the question... sorry took ur time...
Sooo bem, that gives you the SLOPE of the tangent line at x=0, now we need to create an equation for the line passing through that point, with the given slope.
|dw:1351284126936:dw| Hmmm I think you are suppose to get an answer of 3. Check my work a sec, maybe you can tell me what you did differently.
