Question

simplify the expression(cos^2 x + sin^2 x)/( cot^2 x- csc^2 x)

Answer 1

answer is -1. shall i simplify??

Answer 2

yes please and thankyou

Answer 3

cos^2 x + sin^2 x=1
cot^2 x= cos^2 x/sin^2 x
csc^2 x=1/sin^2 x
cos^2 x-1/sin^2 x= cos^2 x - sin^2 x - cos^2 x/sin^2 x= -1
1/-1=-1
do you understand??

Answer 4

yea thanks

Answer 5

you're welcome :)

Answer 6

can you also help me with this problem? Use basic identities to simplify the expression. (cos^2(theta)/sin^2(theta)+ csc θ sin θ

Answer 7

cos^2 θ/sin^2 θ + 1/sinθ * sinθ=cos^2 θ/sin^2 θ+1
cos^2 θ+ sin^2 θ/ sin^2 θ=1/sin^2 θ=csc^2 θ
did you get it??

Answer 8

yeah thanks alot

Answer 9

you're welcome again :)
