solve the following equation in the interval [0,2pi]. Give the answer as a multiple of pi. Do not use decimal numbers

(sin(t))^2=3/4

  • trig -

    Take the square root of both sides.
    sint=sqrt(3)/2

    t = pi/3, 2pi/3

  • trig -

    thats what I did, but it's giving me a wrong answer

  • trig -

    sin t can also be -(sqrt 3)/2. That would correspond to an angle of 4 pi/3 or 5 pi/3

    You did not list all the possible values.
