=Favorite Math Formulas=

On this page each student should list their screen name, their favorite math formula as a displayed equation, and given a sentence or two about why that is their favorite equation. This must be completed by 8/24/11, but of course can be updated at any time during the year.

My favorite math formula would have to be
math c^2=a^2+b^2 math

====This is the Pythagorean Theorem, and it is my favorite because it is so useful in a wide variety of problems. Also, it is simple to use, and it may be manipulated to solve for what you need in the problem.====

__chriss367__ ====My favorite math formula is the Pythagorean Theorem. It's very easy to learn and can be applied to a lot of problems. It's one of the most basic and important formulas in math, and for good reason. a^2 + b^2 = c^2==== =jhhboyle= My favorite mathematical formula is math c^2=a^2+b^2 math i.e., the Pythagoran Theorem, because it has been the most useful formula to me in my time at Uni.

My favorite equation would have to be the quadratic formula because it has a song and it is used in most, if not all, quadratic equations. is one of the best formulas I can think of and is one of the fundemental formulas we need to solve equations of the quadratic persuasion.

math c^2=a^2+b^2-2abCosC

math The law of cosines is my favorite formula because it's a branch off of the Pythagorean Theorem, one of the most mundane theorems of all time. This law is very useful for determining all sides and angles of a triangle when only a few are known.

My favorite formula would have to be $C = 2\pi r$ because it is very useful, especially with the Unit Circle. Whenever working with a circle it is helpful to be able to find the circumference, because you can then use that to find other information regarding the circle or other items in the circle.

__**mestre123**__

math $ My favorite math formula is $\frac{a}{b} * \frac{c}{d}= \frac{ac}{bd}$ because it is useful for multiplying fractions and is very easy to use. math

__**mcbride1995**__ My favorite math formula is the general form equation which is: Ax+ By+ C=0. It is my favorite formula because it can be very useful and I think is the easiest to remember and convert to from slope-intercept form.

My favorite math formula is math d=\sqrt{(x_{1}-x_{2})^{2}+ (y_{1}-y_{2})^{2}} math I really like this formula because it is useful in trying to find two specific points. It's a pretty simple formula but very handy.

__**bissy.michael**__

My favorite math formula is math \frac{sin\left ( A \right )}{a}=\frac{sin\left ( B \right )}{b}=\frac{sin\left ( C \right )}{c} math This is because it makes finding angles and sidelengths in a triangle very easy, it's versatile, the formula can be flipped around, and it's easy to remember.

__Andrew2795__ My favorite formula is the quadratic formula because it is a simple problem that somehow helps with a huge variety of problems.

math x=\frac{-b\pm\sqrt{b^2-4ac}}{2a} math

__nbuss2__

My favorite math formula is the quadratic formula. math x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} math In middle school, we learned a song to help us remember it and since the formula comes up a lot, the song was very useful.

__beshers1__ My favorite math formula is for the area of a circle. math A= \pi r^{2} math

__stavins1__ My favorite formula in mathematics is the formula for the area of the circle. I like this formula because of pi day activities in middle school where we used the formula to divide up a pie into equal slices.

math A= \pi r^{2}

__seeley1073__ My favorite formula is the quadratic formula. That is because it is an easy way to solve quadratic equations. There is also a song about it which means that I will always remember it.

math x=\frac{-b\pm \sqrt{b^2-4ac}}{2a} math

__tarik0219__

My favorite math formula is for the area of a triangle. I remember it being the first formula I learned. math A=base*height*\frac{1}{2} math

__ktecox__ My favorite formula is the ever popular quadratic formula. Not only is this formula very useful in different equations, it also has a song that makes it the most fun out of all the math formulas that I can think of.

math x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a} math

__park229__ My favorite formula is the equation for a circle. I like it because it is generally very useful when working with circles, and because you don't always have to memorize it to know it; you can find it by using basic math.

math (x-h)^{2}+(y-k)^{2}= r^{2} math

__emma.hoyer__

For some reason, I really like the distance formula. It's easy to remember, I can think of plenty of situations in which it has helped me, and it's really hard to mess it up.

math d=\sqrt{(x_{1}-x_{2})^{2}+ (y_{1}-y_{2})^{2}} math

__vickiechang__ My favorite math formula is the Pythagorean Formula because you can use it for different kinds of problems and because it doesn't require a lot of calculation to use. math a^2+b^2=c^2 math

My favorite formula has to be the Quadratic formula $x=\frac{-b\pm \sqrt{b^2{}-4ac}}{2a}$ because it has saved me on a series of math tests and assignments. It is easily the formula that I use the most of all of them that I know.

My favorite equation would be the equation used for graphing parabolas $y= a\left ( x-h \right )^{2}+k$. Graphing parabolas and functions was my favorite thing to do in math last year, so the equation became one of my favorites to use.
