How to solve for x in trigonometric equations
WebFirst, re-write the equation so that it is equal to zero: Now we can use the quadratic formula to solve for x. In this case, the coefficients a, b, and c are a=1, b=2, and c=-3: simplify. This gives two potential answers: and. Sine must be between -1 and 1, so there are no values of x that would give a sine of -3. The only solution that works is .
