A parabola with an equation, y2 = 4ax has its vertex at the origin and opens to the right.
It's not just the '4' that is important, it's '4a' that matters.
This type of parabola has a directrix at x = -a, and a focus at (a, 0). By writing the equation as it is, the position of the directrix and focus are readily identifiable.
For example, y2 = 2.4x doesn't say a great deal. Re-writing the equation of the parabola as y2 = 4*(0.6)x tells us immediately that the directrix is at x = -0.6 and the focus is at (0.6, 0)
The d stands for distance.
E = mc squared is a famous equation devised by Albert Einstein that demonstrates the way in which matter and energy are connected. E stands for energy, m stands for mass or matter, c stands for the speed of light."Energy equals mass times the speed of light squared." On the most basic level, the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
Oops! That's not an equation. It has no 'equals' sign ( ' = ' ) in it, so it's just an 'expression' that stands for a number. The number that it stands for depends on the value of 'x', and any time 'x' changes, the value of the expression changes.
There is no sum of e=mc2, it is an equation concerning matter and energy. e=mc2 stands for: Energy equals mass times the velocity of light squared. E = M C 2
The 'c' in that equation stands for the speed of light in a vacuum. If the equation is being evaluated in metric units, then it's 299,792,458 meters per second. If in English units, then it's 186,282 miles per second.
E stands for "ENERGY" M = "MASS" C = "SPEED OF LIGHT"

A little more info would be nice but as it stands your equation is 2L + C = P

Circle stands for female and square stands for male.
The formula for the Latus rectum is simply 2L = 4a with a stands for the distance of the focus from the vertex of the parabola. Given a, you can simply solve for the length of the latus rectum by using this formula.. L = 2a

It is called a constant.
