Question

3 tan theta under root 3 tan theta is equals to 3 sin theta so find the value of sin square theta minus cos square theta

Answer 1

Check that's solution is write

Answer 2

Square both sides in (√3 tan theta = 3sin theta ) . You will get cos^2 theta =1/3. Then you can find sin^2 theta = 2/3 , and hence sin^2 theta - cos^2 theta = 1/3. Check out the solution for better understanding. Happy to help
