Unit 2 Part 2 Test Reviw

Find the quadrant in which O lies if:

cot( O ) < 0 and cos( O ) > 0

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Answer explanation

Remember the saying: All Students Take Calculus tells you which trig ratio is positive.

So, when is cotangent negative and cosine positive?

Find the quadrant in which O lies if:

csc( O ) < 0 and tan( O ) > 0

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Answer explanation

Remember the saying: All Students Take Calculus tells you which trig ratio is positive.

So, when is cosecant negative and tangent positive?

• Quadrant I

• Quadrant II

• Quadrant III

• Quadrant IV

Answer explanation

Remember the saying: All Students Take Calculus tells you which trig ratio is positive.
