how i can write sine square vs intensity graph?

Answer 1

[Steven Lord]

The square of the sine of an angle:

A = pi/4;
sa = sin(A)

sa = 0.7071

ssa = sin(A).^2

ssa = 0.5000

Note that trying to put the ^2 between the function name and the parentheses wouldn't work. I'm not going to run this because the syntax error would prevent MATLAB from running any code in this Answer.

% ssaWouldNotWork = sin.^2(A)
