Two plus -1 is one, so one, and so what is this going to be? You're gonna get y is equal to 1/6, x minus one, squared, plus 1/2. There you go. That is the parabola with a focus at
Let P (x, y) be any point on the parabola whose focus is (-4, 2) and the directrix x + y – 3 = 0. As we already know that the distance of a point P from focus = distance of a point P from directrix. So, √ (x + 4) 2 + (y – 2) 2 =. On
Explain mathematic equation
One way to think about math problems is to consider them as puzzles. To solve a math problem, you need to figure out what information you have.
Deal with math
One plus one is two.
