Solve the problem.A square wave is built up from sinusoidal curves of varying periods and amplitudes. Graph the following function, which can be used to approximate the square wave.f(x) = 
0 ? x ? 4 
A better approximation to the square wave is given by f(x) = 
style="vertical-align: -17.0px;" />0 ? x ? 4 
Graph this function and compare the result to the previous graph. Adding another term will improve the approximation even more. Write this new function with four terms.
