Practice … WebAug 4, 2024 · The curve, in Cartesian coordinates, is a circle: x 2 + y 2 − y = 0, centered at the point C ( 0, 1 2) and radius r = 1 2. Equalizing t 2 + 1, in the expressions of x and y, we get that t = y x ; replacing t in one of the two coordinates, we get the circumference equation. The point on the curve in t = 1 2, is ( x, y) = ( 2 5, 1 5).
WebIn calculus, “Normal” has a non-intuitive meaning. Normal within this context means perpendicular; a normal line to a point on a curve is a line that: Runs through the point and Is perpendicular to the tangent line. The following image shows the normal line running through the curve and perpendicular to the tangent:
