How can plot integral for sin wave
Show older comments
HELLO
iam plot sin wave signal and used the code in m file:
t=0:0.1:360*22/7/180;
x1=sin(t);
plot(t,x1);
but how can plot integral for sin wave?
please help me

Can you be more specific? Definite or indefinite integral?

Now, I'm confused. You say "how can plot integral for sin wave?" This has to be the indefinite integral. The definite integral is just a number, so do you want to plot something or do you just want a number. Did you see my response below? That finds and plots the indefinite integral.

t=0:0.1:360*22/7/180;
x1=sin(t);
dt = t(2)-t(1);
x2 = cumsum(x1.*dt);
x2 = x2-1-x2(1);
plot(t,x2)
Or
x2 = cumtrapz(t,x1);
x2 = x2-1-x2(1);
plot(t,x2)

x2 = cumsum(x1.*dt);
x2 = x2-1-x2(1); sir can u explain these two lines

f=inline('sinx','x');
syms x;
y=int(f(x),x);
t=0:0.1:360*22/7/180
hold on
plot(y(t),t);
end
