If f (x) = x + tan x and g(x) is the inverse of f (x) then g’ (x) is equal to:
If f (x) is differentiable function and (f (x). g(x)) is differentiable at x = a, then
Determine the value of ‘a’ if possible, so that the function is continuous at x = 0.
Now if it is given that there exists a positive real δ, such that f (h) = h for 0 < h < δ then find f’(x) and hence f (x).
Let f be an even function and f ’(0) exists, then find f’(0).
