Question

Use basic identities to simplify the expression.

sin^2 θ + tan^2 θ + cos^ 2 θ

sec^2 θ

cos^3 θ

sin θ

tan^2 θ

Answer 1

those are the answers up there and the first one is the equation

Answer 2

sin^2 θ+cos^2 θ=1
1+tan^2 θ=1+(sin^2 θ/cos^2 θ)= 1/cos^2 θ=sec^2 θ
do you get it?

Answer 3

why did you put one over tan? Otherwise- i do understand thanks so much :)

Answer 4

my english isn't enough adequate to explain, dude. excuse me :)
