How to simplify a circle equation
WebThe equation of a circle is x2+y2 =r2 x2 + y2 = r2, where r represents the radius (with a centre at 0,0 0,0 ). The definition of a circle is a set of all points on a plane that are a fixed distance from a centre. That distance is called the radius. WebJul 9, 2024 · Because both h and v are zero, they can disappear and you can simplify the standard circle equation to look like x 2 + y 2 = r 2. For instance, to graph the circle x 2 + y 2 = 16, follow these steps: Realize that the circle is centered at the origin (no h and v) and place this point there. Calculate the radius by solving for r. Set r 2 = 16.

WebTo simplify an expression with fractions find a common denominator and then combine the numerators. If the numerator and denominator of the resulting fraction are both divisible by the same number, simplify the fraction by dividing both by that number. Simplify any resulting mixed numbers. WebDec 20, 2024 · The Pythagorean identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan( − θ) = − tanθ.
