Answer 2

Answer:

Step-by-step explanation:

1) in picture

2)

Since root 3 tan θ = 3sin θ

so, root 3 sin θ /cos θ= sin θ

= so, root 3 will cut 3 and sin θ wil be cancelled

= so, 1/cos θ= root3

so, cos θ =1/root 3

so, squaring on both sides:

=cos^2θ= 1/3-------(1)

= 1-sin^2θ= 1/3

=sin^2 θ=1-1/3

= sin^2 θ=2/3--------(2)

so, on subtracting equation (1) from (2):

sin^2θ - cos^2θ = 2/3 - 1/3

sin^2θ - cos^2θ = 1/3
