NettetWe have a circle with radius 1 centered at (2,0). From the Pythagorean Theorem, we know that the x and y components of a circle are cos(t) and sin(t), respectively. Thus we can parameterize the circle equation as … NettetWe know that the general equation for a circle is ( x - h )^2 + ( y - k )^2 = r^2, where ( h, k ) is the center and r is the radius. So add 21 to both sides to get the constant term to the righthand side of the equation. x^2 + y^2 -4y = 21. Then complete the square for the y terms. x^2 + y^2 - 4y + 4 = 21 + 4. century auto service maplewood
