Today I wanted to share with you some random formulas that I found \ made myself to find solutions to problems (or just because I can). So let's get started.
For example if I wanted a conversion formula between and using
Feel free to make your own temperature scale and use this formula.
This one is a little bit more complicated, firstly is approximately but it is also equal to an equation which can be used to give a close (works better with bigger values of ) value to .
The second formula allows you to refine into an even closer approximation of . This formula also includes an 'If' statement located at the where it is either or depending on the outcome.
To use these equations you need to know the closest square before and after , these are denoted by and respectively. The 'If' statement asks whether is true or not, if it is then the becomes a , if it's false then the becomes a .
For example let's try and find
The second equation can be used endlessly but we're only going to use it once. So according to our formula to 4.d.p. The real value for to 4.d.p is
So our equations got close with just one use, so if we use it again
So we are getting closer, just slowly.
That's it for now but I will be updating this when I come up with more formulas.
