Quandaries and Queries


Name: Jenna

Who is asking: Student Level: Secondary

Question: I can't prove

1-sinQ	           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 180o, sinQ = tanQ = 0 and cosQ = -1. Thus the left side is 1 and the right side is -1.
