Question

can someone please explain?

Show that the point (7/25, 24/25) is on the unit circle

Answer 1

x = 7/25
y =24/25
---->x^2 + y^2 = 49/625 +526/625 =1 . x^2 +y^2 =1 means it's is in the unit circle

Answer 2

The equation of the unit circle is x^2 + y^2 = 1
Substitute 7/25 in for x and 24/25 in for y, and see if it makes the equation true.
