Yes, it does: (1+ sin A)/cos A= 1/cos A+ sin A/cos A= sec A+ tan A.powp said:Hello All
I am having problems Verifying this identity
(COS A) / (1-SIN A) = SEC A + TAN A
I can get the RHS = (1 + SIN A)/COS A
But this does not equal the LHS
Any advice is welcome.
THanks
Yes that is perhaps the most fundemental of all trig identities. It's actually just Pythagoras Thm for a RHT with unit length hypotemus.powp said:does [tex]sin^2 a + cos^2 a = 1[/tex] verify the idenity?
