unit circle(x,4) Given a unit circle with coordinates (x, 4), calculate x

Unit Circle Formula

Given a unit circle point (x, y)

x2 + y2 = 1

Plug in x = x and y = 4

x2 + 42 = 1

x2 + 16 = 1

Subtract 16 from each side:

x2 = 1 - 16

x2 = -15

Take the square root of each side:

√x2 = √-15

Final Answer

Not on a unit circle
