Deriv. of (58+Rpi)(500000/pi)(r^-1)+19*pi*r^2, R a constant

[arkansasst555]

I need some help finding the derivative of....

(58+Rpi)(500000/pi)(r^-1)+19*pi*r^2

where R is a constant

Does your problem look like this:

\(\displaystyle (58 \, + \, R\cdot \pi)\cdot \frac{50000}{\pi \cdot r} \, + \, 19\cdot \pi \cdot r^2\)

That looks like C1 r^(-1) + C2 r^2.
