Thanks for helping!
If I have the coordinates (0,7) and I need to use the formula tan theta=y/x, (x cannot equal 0), how do I find the angle? Isn't it undefined? Thank You!

Best ResponseYou've already chosen the best response.1think of it this way: tan = sin/cos for what angle is cos(t) = 0?

Best ResponseYou've already chosen the best response.1no, its the bottom that is zero ... so cos(t) = 0

Best ResponseYou've already chosen the best response.1y/x = sin(a)/cos(a) y cos(a) = x sin(a) since x=0 and y=7 7 cos(a) = 0 cos(a) = 0
