For the cosine case, use the identity $\cos(x) = \cos(x + 2\pi) $ (period of the cosine function is $2\pi$) and plug $\cos(0)$ and $\cos(\pi)$ to verify this.

This is a MPI C++ parallel program that performs numerical integrations. Different functions are included. make. mpiCC -o integrationSample integrationSample.cpp. Here is a sample run: …

How to prove that $$ \int_{t_0}^{t_0+T} \sin(m\omega t)\sin(n\omega t)\,\mathrm{d}t$$ will equal to $0$ when $m\ne n$ and $\frac{T}{2}$ when $m=n\ne 0$? Besides $$ \int_{t_0}^{t_0+T} …

Sep 5, 2015 · Integrating $\int \frac{-\sin x}{1+\cos x}\, dx$, I get $\ln(1 + \cos x)$. WolframAlpha gives $2 \ln(\cos \frac x 2)$. Is WA wrong?

MPI stands for Message Passing Interface. It is a library of subroutines/functions, not a computer language. Programmer writes fortran/C code, insert appropriate MPI subroutine/function calls, …

Learning MPI by Examples: Part II fct(x) = cos(x) !! kernel of the integral integral = 0.0 !! initialize integral h2 = h/2. do j=1,n !! sum over all "j" integrals aij = a + ((i-1)*n +(j-1))*h !! lower limit of …

Utilize the trigonometric identity sin (A + B) + sin (A − B) = 2 sin (A) cos (B) to express sin (n π l x) cos (m π l x) in a different form. Show that integral^l_-l sin (n pi/l x) cos (mpi/l x)dx = 0, for m n. …
