What are the 5 remaining trigonometric functions of θ, given that cos θ = and sin θ > ? Thanks. 
This is a 3-4-5 Pythag triple, and  is in the 2nd quadrant, where cos is < 0, and sin > 0. 

This should be enough for you to figure it out yourself. If not there are tons of similar problems in this site. Just look them up!
