How to plot f: y=e^-x.sin^2x function in matlab?

f: y=e^-x.sin^2x

Please help my computer gives errors and I don't know how to fix them.

Answer 1

[Setsuna Yuuki.]

You should try this

x = 0:1e-3:10
y=exp(-x).*sin(x).^2;
plot(x,y)

Errors to fix (numbers refer to the characters above the numbers)

  f: y=e^-x.sin^2x
%  1   2   34    5

1. f: is not valid matlab syntax. You mean f=
2. if e is a variable, this is OK but if you're looking for exponent, use exp(-x)
3. x.sin is not valid matlab syntax. If you want multiplication, use x*sin (see next point)
4. if 'sin' is a variable, then sin^2 is ok but it's a horrible variable name. If you want to use the sin function, use sin(__)
5. 2x is not valid matlab syntax. Use 2*x if x is a scalar or 2.*x if x is an array. Or, sin(x)^2
