Question

Find the point on the terminal side of θ = negative three pi divided by four that has an x coordinate of -1. Show your work for full credit

Answer 1

\[\theta =-\frac{3\pi}{4}\]?

Answer 2

you got a unit circle cheat sheet?

Answer 3

you do now

Answer 4

Yes, that is the equation :)

Answer 5

take a look at the last page, the unit circle, and locate \(-\frac{3\pi}{4}\)

Answer 6

you see the x and y coordinates of that point?

Answer 7

you have to go around the unit circle clockwise

Answer 8

is it clear what the coordinates of that point are on the unit circle?

Answer 9

No, I'm sorry this whole lesson I'm having a hard time with

Answer 10

it is the same as the point labelled \(\frac{5\pi}{4}\)

Answer 11

in any case you see that both the x and y are the same there

Answer 12

so if the x is -1, so is the y

Answer 13

Oh, okay
