    Derivative ae^(b theta)

    Good afternoon,

    What is the method fo differentiating the following:

     <br />
\displaystyle ae^{b\theta}<br />

    Is it as simple as...

     <br />
\displaystyle abe^{b\theta}<br />

    I was looking for an explanation of the rules involved with this particular situation, but could not find what I was looking for.

    Forgot...

    The a and b are positive constants. So, I would assume that would make my guess as to the answer correct.

    The chain rule

    f(x)=ae^{x} and x=b\theta

    The chain rule gives

    \displaystyle \frac{df}{d\theta}=\frac{df}{dx}\frac{dx}{d\theta}  =ae^{x}b=abe^{b\theta}

    That's what I was thinking... I've been second guessing myself too much.

    Thank you!
