Question

If θ= 60°, then 1+ tan^2θ/2tan θ is equal to...​

Answer 1

Step-by-step explanation:

θ= 60°

then

1+ tan^2θ/2tan θ

tan60°=√3

so

1+(√3) ²/2√3

1+3/2√3

4/2√3

2/√3

Answer 2

Answer:

θ= 60°

1+ tan^2θ/2tan θ=1/sin2θ

so 1+ tan^2θ/2tan θ=1/sin120°

=1/sin(90°+30°)

=1/cos30°

=2/√3

(sin2θ=2tanθ/1+tan²θ)
