OK. I didn't catch what you were doing.I dont think so, because doesnt pcos(phi)=z?
Don't you mean (1 - cos^2(phi))?vela said:Try bringing the (1+cos^2(phi)) to the other side.
It's probably helpful not to change the rho^2 on the left side just yet.bglb212 said:x^2+y^2+z^2=z/(1-cos(phi)^2
Yes, I did. Thanks for catching that.Don't you mean (1 - cos^2(phi))?
That's a very nice thing to say! Thank you!got it, I like you mark. you're helpful. may your children be plentiful and live long
