Скачать или смотреть The partial sum of the Fourier terms of Triangular wave || Scilab #5

This video is about the programming in Scilab for the partial sum of the Fourier terms of Triangular wave.
►The program is:
x=0:0.01:5*%pi
s1=(%pi/2)+(4/%pi)*(cos(x))
s2=(%pi/2)+(4/%pi)*((cos(x))+(1/2^2)*(cos(2*x)))
s3=(%pi/2)+(4/%pi)*((cos(x))+(1/2^2)*(cos(2*x))+(1/3^2)*(cos(3*x)))
s4=(%pi/2)+(4/%pi)*((cos(x))+(1/2^2)*(cos(2*x))+(1/3^2)*(cos(3*x))+(1/4^2)*(cos(4*x)))
s5=(%pi/2)+(4/%pi)*((cos(x))+(1/2^2)*(cos(2*x))+(1/3^2)*(cos(3*x))+(1/4^2)*(cos(4*x))+(1/5^2)*(cos(5*x)))
subplot(511)
plot2d(x,s1,1,leg="s1")
subplot(512)
plot2d(x,s2,2,leg="s2")
subplot(513)
plot2d(x,s3,3,leg="s3")
subplot(514)
plot2d(x,s4,4,leg="s4")
subplot(515)
plot2d(x,s5,5,leg="s5")
