Question

Use basic identities to simplify the expression.
(tan(θ))/(cot(θ))

Answer 1

(a/b)/(b/a) = (a/b)(a/b)

Answer 2

a=tan b=cot?

Answer 3

a = sinx, b = cosx
(sinx/cosx)/(cosx/sinx) = sinx*sinx/cosx*cosx = sin^2(x)/cos^2(x)

Answer 4

sin^2(x) + cos^2(x) = 1
divide everything by cos^2(x) and you have (sin^2(x)/cos^2(x)) = sec^2(x) -1

Answer 5

what is sec^2(x)-1 equal too because that is not an option?

Answer 6

options are:
sec2θ

sin θ

tan2θ

cos3θ

Answer 7

many things, what are the options

Answer 8

tan^2(x) = sin^x*sin^x/cos^x*cos^2x

Answer 9

tank you!

Answer 10

tan^2(x) = sin^2xsin^2x/cos^2x*cos^2x

Answer 11
