# derivative problem

Can anyone help me in solving the derivative of the equation f=sinh(px)*cos(py)/sinh(p)? I need to derive it based on its unit normal vector, means i need the answer of df/dn.

[p =pi=3.142]

Thanks.

i may be wrong, but you just take the derivative of f. that means, if you have F=A/B then F' = [B *(derivative of A)]-[A * (derivative of ] / B^2

in other words: low D high minus high D low all over low squared.
where D means derivative of.

I'm trying to solve it analytically, not numerically.
