These are some of the most famous equations that every man, woman, and child should memorize, or at least have a sense of what they stand for.
E = m * C * C
Energy inherent in matter and convertible from it is equal to the mass of an object multiplied by the square of the speed of light. This is expressed in Newtons.
a**2 + b**2 = c**2
The sum of the square of the sides of a right-angle triangle is equal to the diagonal side squared.
C = V * T * P
Given an amount of gas in a closed chamber, then if you increase the volume, then product of the temperature the pressure will decrease.
A = pi * r ** 2
Area of a circle is its radius squared times pi
FV(m) = m*(1+i)^N
The future value of an investment of m amount of money which bears i rate of interest per period, in N number of periods.
a = d/t^2
Acceleration is the measure of distance travelled per time squared.
f'(x) = (f(x)-f(d))/f(d) where d is approaching zero
The definition of the derivative of a function
I = V/(R1) + V/(R1) + ... + V/(RN)
The current in a circuit, where the resistors are connected in a parallel fashion.
I = V / (R1 + R2 +... RN)
The current in a circuit, where the resistors are connected in a serial fashion.
If a<b, and b<c, then a<c
One of the corollaries of the law of distribution.
