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

Question

Find the point on the terminal side of θ = -3
`\pi`/4 that has an x coordinate of -1.

Answer 1

This is in the third quadrant where the tangent of the angle is positive

tan pi/4 = 1 = y/-1 so y = -1

The required point is (-1,-1)
