Solve the given equation Please put answers separated by com

Solve the given equation. Please put answers separated by comma. Let k be any integer. Round terms to three decimal places.

7 tan() sin() 3 tan() = 0

Thank you!

7 tan theta sin theta - 3 tan theta=0

tan theta(7 sin theta -3)=0

tan theta=0 , sin theta=3/7

theta=pi k , theta=2pi k + pi -sin^-1(3/7), 2 pi k +sin^-1(3/7)
