Evaluating series using the formula for the sum of n squares
WebSep 4, 2014 · We want to break the unknowable sum into a piece that is clear and known and a piece that can be estimated. Then we can use the estimated piece to set a bounds on all the values that the sum can possibly be. You usually cannot just start from n= 1 and keep … Sums of sines and cosines arise in Fourier series. $${\displaystyle \sum _{k=1}^{\infty }{\frac {\cos(k\theta )}{k}}=-{\frac {1}{2}}\ln(2-2\cos \theta )=-\ln \left(2\sin {\frac {\theta }{2}}\right),0<\theta <2\pi }$$$${\displaystyle \sum _{k=1}^{\infty }{\frac {\sin(k\theta )}{k}}={\frac {\pi -\theta }{2}},0<\theta <2\pi … See more This list of mathematical series contains formulae for finite and infinite sums.
