tangent line equations

find the equation of the tangent line to the function f(x)= 5/ (x^2) at the point (1,5).


I tried finding the derivative to get the slope and then using y=mx+b to solve from there but I still am having trouble getting the problem correct.

What did you get for the first derivative?

I got 5h+10 but I'm not sure that right, since I usually have trouble finding the derivative

The fact that you found the derivative to be 5h+10 probably indicates that you are finding the derivative using the limit definition of derivative, i.e. you have not yet learned the power rule for finding a derivative?
