Soil Mechanics- Cohesionless Soil Nphi
Very silly question, but how do we find the angle using calculator. Its a step in a soil mech problem.
2. Relevant equations
The equation is :
Nphi= tan2(45+ θ/2)
given that Nphi= 4.183, the equation becomes
4.183= tan2(45+ θ/2)
How do we calculate this?
Edit: Sorry Mods can you please delete this thread. I figured it out :)
