way to write the equation given below?

H′=(1+εcosθ)-(H_a/c) 〖sin〗^2m [π((θ.n_x)/2π-1)] 〖sin〗^2m [π(z.n_z-1)]

you must use basic operators

[Torsten]

... and you must write in plain ascii.

Didn't @Yogesh Kumar ask exactly the same question 1 week ago?

If the intention is about merely writing the equation in MATLAB script, and not caring about whether the program runs or not (despite the equation maybe written correctly), why not just inserting a line of code here?
