(4 * x^4 - 2 * x^(-7/4) - x^(-2))

Answer 3

[khalid salim]

s = @(x) (1-0.4*(cos(x/100))).*(0<=x & x<=511);

x = linspace(0, 500);

R = s(x);

figure(1)

plot(x,R)

axis([xlim 0 1.5])

% intensity function

f=1/20;

x = linspace(0, 500);

I=@(x) (R(x).*sin(2*pi*f*x));

plot(x,I)

axis([xlim 0 1.5])
