Intro to Csc, Sec, and Cot Trig Graphs

Where is the sine ratio = 0 on the graph?

• x = tt/2, 3tt/2

• x = -2tt, -tt, 0, tt, 2tt

• x = -tt/2, -3tt/2

What is the sin 

• 

• 

• 1/2

Where is the tangent ratio = 0 in 1 positive and 1 negative lap around the unit circle?

• At tt/2 and 3tt/2

• -3tt/2, -tt/2, tt/2, 3tt/2

• -2tt, -tt, 0, tt, 2tt

Where is the tangent ratio = 1 in a positive and negative lap around the unit circle? 

• -3tt/2, 0, tt, 2tt

• -tt/4, tt/4, 3tt/4

• -7tt/4, -3tt/4, tt/4, 5tt/4

Where would the cotangent of an angle = 0 in one positive and one negative lap around the unit circle?

• -2tt, -tt, 0, tt, 2tt

• -3tt/2, -tt/2, tt/2, 3tt/2

• No where
