# Math Help - help with tangent line equation?

1. ## help with tangent line equation?

I can't seem to be able to figure this one out. Could someone walk me through it?

Find an equation for the line tangent to the graph of
at the point for .

=

2. show me the derivative ...

3. 2x(e^x)+(e^x)(2)

4. note that it can also be written as $f'(x) = 2e^x(x+1)$

for $f(x) = 2xe^x$ , $f(1) = 2e$

$f'(1) = 4e$

$y - 2e = 4e(x - 1)$

that's all folks.

5. thank u so very much skeeter. Ur a life saver!!!!!!!!
