Question

if tan theta = √3 find the value of sin 2theta-cos2theta​

Answer 1

Answer:

Step-by-step explanation:

Tan theta = √3

Tan theta = tan 60°

theta =60°

Now, sin 2theta - cos 2 theta

Sin 2× 60° - cos 2 × 60°

Sin 120° - cos 120 °

Sin (180-60) -cos (180-60)

Sin60 + cos 60 = √3/2 +1/2

= (√3 + 1) /2
