Question

1−secθ/tanθ+tanθ/1−secθ=−2cscθ

Verify that each equation is an identity.

Answer 1

mostly algebra i think, little if no trig

Answer 2

if you put \(x=\cos(x)\) and \(b=\sin(x)\) then the left hand sides is
\[\frac{1-\frac{1}{a}}{\frac{b}{a}}+\frac{\frac{b}{a}}{1-\frac{1}{a}}\]

Answer 3

ok, I can see where you are going with this:)(:

Answer 4

multiply the top and bottom of both parts sides by \(a\) and you get
\[\frac{a-1}{b}+\frac{b}{a-1}\] then go ahead and add them

Answer 5

ok! i understand! thank you!

Answer 6

yw

Answer 7

like i said, almost no trig
maybe on trig step at the end
