Question

find the equation for a line that is tangent to the graph y=e^x and goes through origin

Answer 1

argh. I can't remember how to differentiate y = e^x. Do you know?

Answer 2

\[e^x\]

Answer 3

Thanks! :)

Answer 4

?

Answer 5

sorry

Answer 6

\[y=e^xx+0\]

Answer 7

Is that the equation of the tangent line through the origin? That doesn't seem like it would be a linear equation.

Answer 8

they meet at \[e^x=e^xx\]
\[x=1\]
\[y=e\]
hence equation is
\[y=e\]

Answer 9

\[y \approx2\]
