Question

How do I find the R'(30) and R'(75) from a graph of R(t)?

Answer 1

Oh shoot here it is. Its attached to the rest of the project i'm working on

Answer 2

The slope or differential.

Answer 3

Take the slope

Answer 4

R(75)-R(30)/(75-30)

Answer 5

I get that, but I'm not sure that is what my professor wants. I think I need each one on its own.

Answer 6

For R'(30):
find the slope from t=15 to t=30, then find the slope from t=30 to t=45. Average those two numbers.

Repeat for R'(75).
