Solve the trigonometric equation 3sinθ=1.2 for 0≤θ≤4π

  • math - , Monday, March 31, 2014 at 10:25am

    3sin = 1.2
    sinØ = .4
    (set your calculator to RAD)
    Ø = .41152 or π-.41152 which is 2.73008

    but you wanted from 0 to 4π
    so add a period , or 2π, to each of the above answers

    Ø = .41152 , 2.73008 , .6947, and 9.01326
