please can any one to give me the final expression of S

p,R,t,u,v is constant
Beta and teta is angle changes from zero to 90°

2. ## Re: urgent

Looks like straight forward algebra to me! Do you know how to square something like $\displaystyle 1+ sin(\theta)$?

3. ## Re: urgent

i'd like to plot this:

to abtain this

What's stopping you?

5. ## Re: urgent

i want expression of F(beta,teta) ,and how i can separate this angles

6. ## Re: urgent

Your formula tell you exactly what to do to find S. It is tedious but you should know how to do it.

exactly i want ,how i can do it ,!!!
