Calculate the fourier cosine series, Mathematics

Assignment Help:

The Fourier series expansion for the periodic function,

f(t) = |sin t|

is defined in its fundamental interval. Taking π = 3.142, calculate the Fourier cosine series approximation of f(t), up to the 6th harmonics when t = 0.79. Give your answer to 3 decimal places.
