anonymous · Answer

i know what the unit circle is but how did you know it was in the 2nd quadrant

anonymous · Answer

look at the angle measurements. 3π/4 is in the second quadrant (135°)

anonymous · Answer

but its negative

anonymous · Answer

it is in 3rd

anonymous · Answer

oh I missed that :( sorry. It is in the 3rd then

anonymous · Answer

-3π/4 is the same as 5π/4

anonymous · Answer

y=x tan(θ )

anonymous · Answer

thats how you find the terminal side?

anonymous · Answer

x=-1
the point is (-1,y)

anonymous · Answer

so to find y i just use that equation?

anonymous · Answer

yes. The terminal side is basically the angle. And you can use that formula to find y

anonymous · Answer

okay thank you so much
