How do I find the max value and the unknown variables of f=-cos(theta_A).cos(theta_B)-sin(theta_A).sin(theta_B).sin(phi_A).sin(phi_B)-cos(phi_A).cos(phi_B).sin(theta_A).*sin(theta_B)

Where theta_A, theta_B, phi_A, phi_B are unknown variables. So i put the range for theta =0:0.01:pi and phi =0:0.01:2*pi. Please tell me how to put the code , i would be appreciate. Thanks

One solution is

theta_A=pi, theta_B=phi_A=phi_B=0

Hi How they are 0? As i need to find max value which should be 2*sgrt(2). Could you please tell me the right command how to find the max value of multi-variable function. Thanks so much.
