Active earth pressure is directly proportional to cot2 (45° + φ/2) or tan2 (45° - φ/2).

What is this process?
Zatak said:

Active earth pressure = ka*y*h where ka = (1-sinφ)/(1+sinφ) = tan2(45° - φ/2)

What is equation of passive earth pressure?

@Tanupa. Passive earth pressure = Tan^2(45+ angle\2).

Ka = 1/tan^2(45 + φ/2).

Right. Thanks for the given explanation.

Hers, cot^2(45 +B÷2 ) or by converting cot into tan^2 (90 -45 - B÷2) = tan^2 (45 - B÷2).

Y and h are constants.

The value. Tan^2 (45 +φ/2) is for passive earth pressure.
