comment Find the acute angle of intersection of the curves $y=\cos x$ and $y=e^{-x}$ at the point $(0,1)$.
why is $45^{\circ}$, it is because $tan(1)=45^{\circ}$? thx

comment Determining the derivative of $e^{5x}\tan(2x)$
So, it should be $e^{5x}tan2x$! and the question from paper is mistake! thx

I don't know, In the question it is like that exactly. It is possible mistake?

comment Determining the derivative of $e^{5x}\tan(2x)$
does it mean - $e^{5x}tan2x+5tan2$ by using product rule. sorry if wrong.

comment Determining the derivative of $e^{5x}\tan(2x)$
the problem is $e^{5x}.tan2x$ is not $e^{5x}$ x $tan2x$
