Power series for trig functions
Calculate the coefficients of the Taylor series for the functions sin(θ) and tan(θ) through the order θ^{4}. 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(θ^{3})?
