Solve for theta.

6 sin theta-1=2 theta +1
0 ≤ theta < 2 pi

Please show the work as equations. Give the exact radian measure and no decimals.

impatient much?

Once is enough, thank you.

and you haven't fixed your typo.
3sinθ = θ+1
which does not have an exact solution
θ = -2.585, 0.538, 1.868

its supposed to be 6 sin theta-1=2 sin theta +1
