12. Without using a calculator, determine two angles between
Step 1 :Since the cosecant is the reciprocal of the sine function, we need to find two angles with a sine of
Step 2 :First, let's find the reference angle, which is the angle with a sine of
Step 3 :Now, we need to find the angles in the third and fourth quadrants with this reference angle. The angles are
Step 4 :
