Question

Find the point on the terminal side of θ = -3π / 4 that has an x coordinate of -1. Show work

Answer 1

Answer:

  (-1, -1)

Step-by-step explanation:

One way to write the relationship between the x and y coordinates and θ is ...

  tan(θ) = y/x

Then ...

  y = x·tan(θ) = -1·tan(-3π/4) = -1·1

  y = -1

The coordinates of the point on the terminal side are (x, y) = (-1, -1).
