My Dear Expert Sir what is the easy way to derive formula of a circle.
what is the easy way to derive formula of a circle?
The standard form equation of a circle is a way to express the definition of a circle on the coordinate plane. Remember that a circle is a locus of points. A circle is all of the points that are a fixed distance, known as the radius, from a given point, known as the center of the circle. On the coordinate plane, the formula becomes (x-x0)² + (y-y0)² = R², where (x0;y0) is a the center of the circle. Here we used the Pythagorean theorem.
