I used Mathematica for that partial derivative. you say it is wrong. Then show the corrcet solution. please I have to do this otherwise I will fail and I lose my scholarship.

equations I found is the solution of my equations not the one you suggested me to solve The equation I found is that the linearized one of the non-linear equations. I just asked that is that true ? could you check it ?

Hi tiny-tim, Finally, I have calculated equations but I don't have any idea about whether they are correct or nor. Atleast could you check it please ?

hi tiny-tim I'm begging you please. It's very important for me. I have to finish this before the sun rises :smile:. Again I'm saying I'm not good at mathematics. There is someone who waits for answer. :smile:

if I said no, would you angry of me ? :smile:

hi ,tiny-tim. Thanks for your effort again but I said that I was not good at mathematics. I can not take the partial derivative :) of that function. could you please explain a bit further. kind regards.

thank you so much for your effort. I'm going to try to do but its not going to be easy for me. But the point I smash is that I can not plug that functions into the expression you define above. Can you please a bit help :)))

Revised Question... This is the clear definiton of my problem.. Does Anyone Know the solution ?

Thanks for your interest to help me. I'm sorry about the insufficient information. The "y" and "c" terms are constants. Then, there are only 2 variables, x and θ. Can you help me further from that because I am not good at mathematics.

As you see equations are non-linear. I need equations like in the picture below. I heard that it can be made by using taylor series.

Is there anyone that can help me about linearization of the equations around x=teta=0 ? It is a bit urgent. I am waiting answer from the calculus experts.
