how do I code sin(theta)/cos(theta)?

I would like to create an array with values for both theta(sin^2/cos^2), so I get values for 6 input values.

x=[0.51 0.71 1.0 0.71 0 -0.71];
y=[0.87 0.71 0 -0.7 -1.0 -0.7];
sind^2 (x)
cosd^2 (y)
x+y;

I continue to getting errors to this effect.

   sind^2 (x)

  Error: Invalid expression. When calling a function or indexing a variable, use parentheses. Otherwise, check for mismatched delimiters.

The correct way to square the function in MATLAB is as follows

sind(x).^2

apart from that, you didn't include you function handle which is causing the error. Also see the difference between element-wise multiplication and matrix multiplication in MATLAB
