science Your favorite math equation

I don't know how many eggheads who enjoy this sort of things are here, but let's try.

Mine is this:

Oh yes I really do love math equations a new found passion when I took extra classes at my university. Math was definitely a priority essentially I do more in regards to the field of business. That said one in particular I do like is a very simple one a simple 3d graph with x, y and z to just then put any equation and see what it graphs. 

Though in regards to mathical equations I found Taylor and Maclaurin to be particularly interesting to solve essentially any math that is indefinite or has many lengths of math to solve are interesting brain puzzles. 

I also find exponential equations to be fun although I mean we all have a favorite and to me that might have to be the Z=XY then to pretty much add any values of course when it comes math in regards to graphs especially with many values. Of course somewhat difficult explaining as I am not American so it is difficult for me to explaib in a sense. There are some equations that go on as such f'(x,y) + f''(x,y) + f'''(x,y)+ f''''(x,y)+ f'''''(x,y) so more variables definitely are interesting when it comes to graphing these mathical equations. 

I also enjoy net present value I enjoy most if not every math equation there is, unless however there is some complications of certain values that are given but they try to make it complicated without actually adding persay to the equation itself.

Then of course Einsteins famous formula for general relativity E=MC^2 Energy equals mass times the speed of light. Definitely an equation and a theory I've been rather interested in lately especially related to potential space travels as essentially Einstein is saying nothing can travel faster then the speed of light however this theory does not apply out in space as there have been particulars that have indeed traveled faster then the speed of light. While it is interesting to me the theory I am pretty sure was stated to apply on Earth I mean that's how the theory was created by observation on Earth.

My favorite equations are the ones that I can do reliably and get the correct answer.

The ones that say “undefined” so I don’t have to do as much work.

The ones set up where it only takes one or two steps to solve for x are good too cause it’s just basic addition/subtraction/multiplication/division

[Silly Druid 6,979]

I like equations that describe a relatively simple situation, but something unexpected happens in it. Like the one from my first post, where the third power is "magically" replaced by second power. Here is another example where multiplication becomes subtraction:

(For example: 1/2 * 1/3 = 1/2 - 1/3)

[Fluttershyfan94 5,742]

I also enjoy integrals and derivative, mainly as they feel to me like a bit of a dance one goes forward another goes reverse. 

It is essentially perhaps the most common headache for a lot of people I suppose to differentiate when learning about derivative and integrals. I for one always liked to think of it as such derivative is reverse and integral is forward while remember to add the extra lettering usually "C" as if you didn't do that it wouldn't be correct answer to it as the C is the unknown constant needed for the math equation. While integrals and derivatives are relatively simple their purpose are useful when we are working on statistical analysis. Which is commonly used when we are working on data for either our thesis or any essay requiring statistical analysis I believe firmly in the importance of it. I've always felt like reading from normal distribution or any distribution can be somewhat difficult without the equations that is.

Quadratic formula. I still remember that to the Notre Dame fight song because of a teacher in 10th grade.

In daily life though, my favorite types I actually use quite often are a²+b²=c² and some stuff with π when designing/making something.

@Cirrus. That's some nice memories, quadratic formula definitely very useful but it also happens to be perhaps one of the first more complex formulas we learn and as we achieve that we've somewhat learned the steps to solving it. I for one, definitely was among the first I learned alongside Pythagoras rule.

None. I very much hate math.

i agree with you here lucky!

I also hate math

I like math when it was just 2+2= fish

and it was delicious!

@Fluttershutter What does it mean? There isn't even an equal sign in it...

Look up the meaning of each individual symbol.

OK, I get it now. I wouldn't call it an equation though.

Sorry. Just being funny.

Here's a cool one I just came across in school this week.

Fibonacci numbers are pretty cool!

[Silly Druid 6,979]

Here's a famous one, but in a different version, because I'm a strong Tau supporter.

It connects 4 very important numbers in one simple formula: two fundamental mathematical constants (e and tau), the imaginary unit i, and the "real unit" 1.

I like Pi

Who doesn't?

Twilight prefers Tau.

One step equations are the best. 

 

             9 - x = 3

           + 3       +3

             x    =    6

[Silly Druid 6,979]

@Twilight Sparkle97 I don't understand something here, if you add 3 to both sides, you get 12 - x = 6. Of course the answer is 6, but I don't think it counts as "one step".

The sum of all counting numbers equals:

We need not go any further than 0 + 0 = 0. Math is the bane of my existence, and it is pure evil. Stay away from me, math! *holds up cross in defense*
