a_sym(n) = (1/Pi)*int(f*cos(n*x),x,-Pi,Pi) a_sym(n) = b_sym(n) = (1/Pi)*int(f*sin(n*x),x,-Pi,Pi) b_sym(n) = Now define the values of x to make the plot ThemeCopy xvals = -pi:.01:pi; Now we loop over the CFS coefficients to sum them all up over...
Step 1: Rewrite Cosecant in Terms of SineWe know that:cscx=1sinxThus, we can express the series as:n−1∑k=0csc(2kθ)=n−1∑k=01sin(2kθ) Step 2: Use the Identity for CosecantWe can rewrite csc(2kθ) using the identity:cscx=2cosx2sinxThis gives us:csc(2kθ)=2cos(2k...
