Question

I need to find al the values of theta in radians with -2pi<theta<2pi such that sin=0.5. The homework is due by midnight tonight

Answer 1

-2pi < x < 2pi

sin(x) = 1/2

x = pi/6, 5pi/6, -11pi/6, -7pi/6

Answer 2

Find all values of θ in radians with -6.28<θ<6.28 such that tan(θ) = -7.6. Enter your answers as decimal values correct to the nearest .001 with the values separated by commas.
