Calculate the first order forward difference quotient of f at x:

function should accept a function handle f, an array of points x, and a float h; each should return an array of the difference quotients evaluated at each point in x. To test your functions, approximate the derivative of at each point of a domain over [-pi , pi]. Plot the results

f x + h) f(x))) h f(x) = (sin(x) + 1) sin(cos(x))
