I have a cosine wave of 50Hz and and 1000 Amplitude. It is a AC voltage. I need to integrate it. I know that it would be the sine wave but i don't how to makethat. I have written the cosine wave part which is given below:
clc
clear
f=50;
a=1000;
dt=0:1e-6:40e-3;
V1=a*cos(2*pi*f*dt);
plot(V1)
How can I do the integration after that?

Ran in:
One way to ingegrate the ‘V1’ vector is to use cumtrapz —
f=50;
a=1000;
dt=0:1e-6:40e-3;
V1=a*cos(2*pi*f*dt);
figure
plot(dt,V1)
V1i = cumtrapz(dt,V1);
figure
plot(dt,V1i)
.
