How can do I write a program to plot a graph between the fluctuation and time . The output graph should be a sine wave aswell

T=0:2500:10000;
F(T,z)=summation n=0 to infinty .*(100./factorial(n)).*(1-cos(10.*T).^2)+(sin(10.*T));
plot(T,F);

You write F(T,z) = something, but the right hand side does not involve z ?

Please check your formula again, paying attention to exactly what expression is being summed.

With the expression that you provided:

T=0:2500:10000;
sT = sin(T);
F = sign(sT) * infinity;
plot(T, F);
