Power series for trig functions

Calculate the coefficients of the Taylor series for the functions sin(θ) and tan(θ) through the order θ4. Sketch graphs of each of the functions together with the approximations provided by the truncation of the power series you have obtained.

For what values of θ is an approximation of O(θ) good for these functions? an approximation of O(θ3)?
