Prove the identity:
when
so
on the next one ... is this equation correct as given
before we see if it can be proved
1 - 2 secx - 3secx^2x/ -tanx^2 = 1 - 3secx/ 1 - secx
Hi will someone please help me with thease two problems.
The book says
Prove the identity: 1 + cscx/ secx = cosx + cotx
and
1 - 2 secx - 3secx^2x/ -tanx^2 = 1 - 3secx/ 1 - secx
Thanks and explanation and final answer would be great.
