In the 2nd quadrant of the unit circle, identify which of the following are true. Select all that apply

Question

A) Cosine is positive

B) Cosine is negative

C) Sine is positive

D) Sine is negative

E) Tangent is positive

F) Tangent is negative

Answer 1

B, C and F are correct

rest are false

In Quadrant II, let h= hypotenuse = 1> 0, opposite side = x<0, adjacent side = y>0

sin(theta) = opposite side/hypotenuse= y/h = positive/positive >0

cos(theta) = adjacent side/hypotenuse = x/h =negative/positive <0

tan(theta) = sin(theta)/cos(theta) = positive/negative <0

sine >0

cosine<0

tangent<0
