equations and corresponding graph is given in attached file and i am trying like this but unable to find second graph where is wrong,, please help
%reflection function
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])

I=@(x) s(x).*sin(2*pi*f*x);
plot(x,I(x))

For Sheet 1, Creating Formulas:
1. 10 (A1) + 2 (B1) = __ (C1)
2. 10 (A2) - 2 (B2) = __ (C2)
3. 10 (A3) x 2 (B3) = __ (C3)
4. 10 (A4) / 2 (B4) = __ (C4)
5. 10 (A5) ^ 2 (B5) = __ (C5)

-2xsin(x^2)+cos(x^2)-((e^sqrt(x))/2sqrt(x))+3x^2-8x=0
