Whether you were a math fan in school or you would find any excuse to get out of it, there’s no denying that there are some amazing things that can be done with mathematics, especially equations which are not only able to solve complicated problems for us but can also be an interesting puzzler for the brain. We take a look at 5 different maths equations which certainly have the ‘cool’ factor.
1. The Pythagorean Theorem
You probably all remember this one from school – this is the equation which allows you to work out the angles of a triangle based on the theory that the hypotenuse is equal to the sum of the angles of its legs. If you were always amazed by how this equation could be used to work out these angles, then you’ll be amazed by what it’s used for today. The process of triangulation is central to GPS systems, allowing us to more easily pinpoint our exact location. Without it, who knows how we would ever find out where we were going?
π = 3.14159
Pi, as we all know, is the ratio of a circle’s circumference to the diameter, but is one of the most famous equations for its infinite number, or so it seems. Pi is a number which can be calculated infinitely, although there isn’t necessarily a need to, and the most it has ever been calculated to is 17 million digits, which was way back in 1985. But if you factor in a time before computers, where making these kinds of numbers was much harder
3. Imaginary Numbers
There is such a thing as imaginary numbers, and which the square root is always negative. This allows us to work out complex analysis, especially in the world of engineering. In fact, most of our favourite gadgets and technology products from lights to digital cameras and iPhones, may not have been possible without this equation.
4. Zero Division
? ÷ 0
One of the most puzzling equations is the one in which it has two basic answers. Whilst the answer will always be zero – technically you could take zero out of something endlessly, making it a puzzling equation. It is an equation which has often puzzled people and a good way to spend your hours clawing away at trying to find an answer.
5. The Wave Equation
How can something we feel or see be turned into an equation? Nearly everything we do can be put into numbers somehow but an equation for describing the way in which a wave works is quite a puzzling one. Originally composed to describe the vibrations of violin strings, it is now used as an effective equation for analysing earthquakes, ocean waves and much more – providing an excellent way for oil companies for example to carry out explosions.
Who said maths was boring eh? The equations we learnt in school may not have seemed like they meant much at the time, besides and excuse for doing homework anyway. But they can be applied to a number of everyday situations and are responsible for much of the technological developments that we enjoy today. Have any of your own to share? Please let us know!
