find all values of theta less than or equal to 360 and great

find all values of theta, less than or equal to 360, and greater than or equal to 0, when csc(theta) = root 2.

Solution

csc(theta) = root 2.

so theta = 45 degree

For secound quadrent csc is positive

so thete in secound quadrent is [180-45]

therefor theta = 135
