Question

if √3tan,theeta =1, then find the value of sin^2theeta - cos ^2theeta.​

Answer 1

Answer:

-1/2

Explanation:

Answer 2

Answer:

-1/2

Explanation:

√3 tan θ = 1

⇒ tan θ = 1/√3

⇒ θ = tan-1 (1/√3)

[Taking tan inverse]

⇒ θ = 30°

To find value of sin2 θ – cos2 θ, substitute value of θ We get,

sin2(30°) - cos2(30°) = (1/2)2 – (√3/2)2

= 1/4 - 3/4 = -2/4

= -1/2
