Solve the equation for x if 0 x 2 Give your answer in radia
Solve the equation for x if 0 x < 2. Give your answer in radians using exact values only. (Enter your answers as a comma-separated list.)
2 cos2 x 3 sin x 3 = 0
Please show your work, thanks!
Solution
2cos2x - 3sinx -3 = 0
2( 1 - 2sin2x) - 3sinx - 3 =0
4sin2x + 3sinx + 1 = 0
this gives no any real value of x. so no solution
