Got two problems for extra credit that I can't seem to figure out if anyone here can.
Prove the following.
1. cosx-(sinx-1)/cosx+(sinx-1) = sinx/1-cosx It says as a hint to multiply
the numerator and
denominator of the left side
2. cotx/1-tanx + tanx/1-cotx - 1 = secxcscx
If anyone happens to know how to do these, please let me know, thanks.
