One Problem States:
1. F(x) = 1/x , a=2
By Using The definition of a derivative
do i have to multiply the denominator and numerator by a fraction? Im getting a bit lost here and its not a good sign...
there is another problem that says to use the alternate definition of a derivative where the numerator has f(x) - f(a), instead of (x+h). and to find the derivative at the point:
2. (with the same problem above.)
What Is The Difference and what accounts for that difference?
