    Angles part2

    Find all the angles Theta, with 0 <=theta<=2pie radians, that satisfy each equation.
    (Use radians not degrees. Round your answers to four decimal
    places. Separate multiple answers with a comma.)
    (a) sin theta = -1
    (b) cos theta = 1
    (c) sin theta = 0.4
    (d) cos theta = -0.6
    (e) tan theta = -2.5

    (c) sin theta = 0.4
    (d) cos theta = -0.6
    (e) tan theta = -2.5
    (a) \sin \theta = -1

    \theta = \pi

    (b) \cos \theta = 1

    \theta = 0


    (c) \sin \theta = 0.4

    \theta = 0.4115\; radians

    do the rest of the parts in same way
