Right. Get it now. Thanks.

Thanks for answering, everyone. zoki85, that is very neatly done. Turns out we didn't need the cosine rule at all. Filip Larsen, yes it is established that tan (45 - θ) = x / ( x + y ). But after expansion, we are left with (1 - tan θ) / (1 + tan θ ) using this formula... If you have an...

< Moderator Note -- Thread moved from the technical math forums (that's why the HH Template is not shown) >[/color] It's supposed to be a simple problem. But I can't for the life of me figure out how to go about it. I managed to find out cos θ using the cosine rule, but it is a very long...

OMG how unbelievably stupid of me... obviously (a - b)(a + b) thanks a lot bro... :D

Homework Statement I have to prove that: (sinθ/(1-cotθ)) + (cosθ/(1-tanθ)) = cosθ + sinθ Homework Equations The Attempt at a Solution Here's my attempt at solution...
