If a function `f: [-2a, 2a] -> R` is an odd function such that, `f(x) = f(2a - x)` for `x in [a, 2a]` and the left-hand derivative at `x = a` is `0`, then find the left-hand derivative at `x = -a`.

In a function f : [-2a, 2a] rarr R is an odd function such that f(x) = f(2a - x) for x in [a, 2a] and the left hand derivative at x = a is 0, then find the left hand derivative at x = -a,

If f :[ - 2a, 2a] to R is an odd function such that f (x) = f (2a -x) for x in [a, 2a]. If the left hand derivative of f (x) at x =a is zero, then show that the left hand derivative of f (x) at x =-a is also zero

Find the derivative at x = 2 of the function f(x) = 3x.

If f(x)=|x|+|sin x| for x in(-(pi)/(2),(pi)/(2)) then its left hand derivative at x=0
