Homework problem


i have difficulties in the homework in a geotechnical course, can anyone help? The question is to prove the Coulomb coefficient of active lateral earth pressure Ka=(some relation with sin angles). It is really a mad trigonometry question. Does anyone have the solution to it?

For me, this is not a difficult trigonometry question as long as you know what to do. There is formula to follow so that you can solve your homework. According to my research, Coulomb coefficient of active lateral earth pressure is: σz - vertical geostatic stress cef - effective cohesion of soil Ka - coefficient of active earth pressure Kac - coefficient of active earth pressure due to cohesion
