Novice Calculus

Hi, wondering if anyone has the patients to help me start this question. I am trying to help my Niece but not being much help at the moment!

Question
The resistance R of an electrical conductor at temperature θ^oC is given by R = R_oe^αθ. In this equation α is a constant and is equal to 1.215 x 10^-4 and R_o = 5 x 10³ ohms.


i) Plot the change in electrical resistance as a function of temperature between θ^o = 0^o and θ = 3500^o and find the change in electrical resistance with temperature at a temperature of 1500^o,
ii) Compare your graphical result to those calculated using calculus.


Any help would be gratefully received
