1. ## Another Help on these Pre Calc Problems Plz thank you?

1.) express tan 0 csc 0 in terms of sine and cosine, then simplify the expression.

2.) the terminal side of an angles ot t radian lies in quadrant IV on the line through the origin parallel to -4y - x = -9. find sint t, cos t, tan t.

2. 1. Do you know how to express $tan\theta$ in terms of sin and cos? What does $csc\theta$ represent? Surely you can do this and do the algebra.

2. Pick an (x,y) coordinate such that it's situated in quadrant IV, i.e. a positive x with a negative y. A triangle can be created using the values of x and y and then it's a matter of applying the definitions of sin(t), cos(t), and tan(t).

3. I'll do that but I might still need some more help so can you plz posting?

4. Show us what you've done and we'll see what we can do

5. so far i have y=x/-4+9/4 than i graph it now im stuck
