Name: Jenna Who is asking: Student Level: Secondary Question: I can't prove 1sinQ 1  = tanQ +  1+sinQ cosQ can you help me with this? 

Hi Jenna, I'm glad that you can't prove it because it isn't true. When Q is pi radians, that is when Q is 180^{o}, sinQ = tanQ = 0 and cosQ = 1. Thus the left side is 1 and the right side is 1. Cheers,Penny
