PREDICT NEW FONCTION WITH DEEP LEARNING

I want to find a function h that does not depend on aztan

I have this function

 h=acos((sin(w*pi/180)*cos(de))/sin(aztan))

where

 aztan=atan(sin(w*pi/180)/(sin(phir)*cos(w*pi/180)-cos(phir)*tan(de)))

w=hour angle, de=declinaison, aztan=azimut, phir=lattitude

Can you just do this:

w = 2.3; % [deg] hour angle
de = deg2rad(65); % [rad] declination angle
phir = deg2rad(45); % [rad] latitude

h=acos((sind(w)*cos(de))/sin(atan2(sind(w),(sin(phir)*cosd(w)-cos(phir)*tan(de)))))

h = 1.2210
