Question

can any one please tell me about how to do "Numerical Differentiation by using Central Difference formula"

Answer 1

Example:
f(x)=e^sin(x)
an approximation to f(0.5) can be obtained if we know f(0.6) and f(0.4) using the given formula, with h=0.1
f'(0.5) = (f(0.6)-f(0.4))/(2*0.1) [approximately]
