Thank you so much for your help, You were the 3rd person I asked, and the only one who actually knew how to solve this, you are the man, thanks again.

(1+cosx)(tanx)---------------tanx + cosxtanx---------------tanx + cosxsinx/cosx cancel out the cosx and you get tanx + sinx

you get \frac{sinx}{1+cosx} Then I reduce the right side to the same thing, right?

Then I want to get \frac{sinx(1-cosx)}{(1+cosx)(1-cosx)} correct?

I'm sorry, I don't follow any of this, Normally I understand this stuff, but this "puzzle" is just confusing me \frac{\frac{sinx}{cosx}-\frac{sinxcosx}{cosx}}{\frac{sinx^{2}}{cosx}}

So I'm suppose to reduce the left side to \frac{\{sinx-sinxcosx}{sin^2 x} and then do that to the right?

Am I aloud to multiply the sinx/cosx before finding common denominators with -sinx? \frac{\{sinx-sinxcosx}{cosx} Is this what you mean?

What does LHS stand for?, and I have converted the tanx's to sinx/cosx, but there are so many ways to go from there, I just can't seem to get one, Can you possibly tell me the final simplified version of either side that you got?

Thank-you for moving this thread to somewhere more relevant, and for your input. If I wrap wire around the nail 3 or 4 times instead, will it create a stronger field? I'm using the wie you find inside ethernet cable, Is that sufficient or should I use something else?

So I have a project over the holidays, received it on Friday, I have to build a simple Dc Motor. Using the textbook as a guide has proven to be very difficult because it does not explain itself very clearly, I was hoping some one could provide me with some clarrification. Here are the...
