what are some famous mathematical equation?

Question

i.e. e-mc(Squared). any other that is famous?

Answer 1

e=mc^2
a^2+b^2=c^2 (pythagorean theorum)
y=mx+b (linear equation)
lw+bh=A (area of sqaures and rectangles)
1/2bh=A (area of triangles)
y=x^2 (parabole equation)

Answer 2

I don't know much about mathematics, but I like belove equations

1^1 + 2^1 = 3^1
3^2 + 4^2 = 5^2
3^3 + 4^3 + 5^3 = 6^3

9^3 + 10^3 = 12^3 + 1^3

Answer 3

A squared + B squared = C squared (((Pythagorean theorem, by Pythagoras)

Answer 4

The definition of pi...very hard to write here...it is NOT pi=3.14 but

symbol for pi=c over d....is my understanding this can cause pi to be carried out to over 10,000 digits

Answer 5

I like Euler's formula:

e^(i*theta) = cos(theta) + i*sin(theta)

I always use it instead of trying to remember those crazy trig identities for sines and cosines of sums or differences of angles. Just expand

e^(i*[theta+phi]) = cos(theta+phi) + i*sin(theta+phi)

and collect real and imaginary terms and you have the identities without having to try to remember them.

Answer 6

e^(j*pi)-1 = 0

This one's cool because it contains so many of the fundamental constants of mathematics.

Answer 7

pi r squared

Answer 8

hypotnuse(squared)=base(squared)+altitude(squared)

area of a rectangle=length*breath

Answer 9

sin(sq)theta+cos(sq)theta=1
