Integration is used to compute areas and volumes (and other things too) by adding up lots of little pieces. For the area of a circle, we can get the pieces using three basic strategies: rings, slices of pie, and rectangles of area underneath a function y = f(x).
The formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
The equation of a circle written in the form (x−h)2+(y−k)2=r2 where (h,k) is the center and r is the radius. The circle centered at the origin with radius 1; its equation is x2+y2=1. The equation of a circle written in the form x2+y2+cx+dy+e=0.
Factoring formulas are used to write an algebraic expression as the product of two or more expressions. Some important factoring formulas are given as, (a + b)2 = a2 + 2ab + b. (a - b)2 = a2 - 2ab + b.
The equation of a circle is given by (x−x1)2+(y−y1)2=r2 ( x − x 1 ) 2 + ( y − y 1 ) 2 = r 2 . If center is at origin, then x1 x 1 = 0 and y1 y 1 = 0. Answer: The equation of the circle if its center is at origin is x2+ y2= r2.
The equation of a circle with centre (a, b) and radius r is (x - a)2 + (y - b)2 = r2. For example, the equation of a circle with centre (3, 0) and radius 4 units is (x – 3)2 + y2 = 16. The General Form of the equation of a circle is x2 + y2 + 2gx +2fy + c = 0.
We 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. Then complete the square for the y terms.
What is Process of Factoring? Factoring is a financial transaction in which a business sells its accounts receivable (invoices) to a third party, called a factor, at a discount.
