Hello good day,

I am having issues on how to enter this equation into MATLAB.

I have it as

H/2 * cos(k*x)*cos(sigma*t)

but getting a different answer from my calculator

Thank you

Is your calculator computing the cosine of angles in degrees (which in MATLAB is the cosd function) or in radians (cos)?

I did it in radians and degrees and got different answers.

Am I tryping out the code corretly in MATLAB?

I don't know if I need to put the .* in the function.

If your inputs are all scalars then you can use either * or .*

If your inputs are not scalars, then you need .*
