Nice! In what language are you writing this? And do you have an indication of the speed?I don't have addition/division, but my guess is that it will be fine. Basically, it will always take longer for you to type the number then for the program to compute :3
regarding trig, you can find various articles on the internet, mostly they're an approximation with exponents (If you want to derive them
yourself, you'll need to use taylor polynomals ).
For exponents you'll only need to impelemnt ln(x) and e^(x), since you can rewrite any log(x, y) and x^y to a form using ln and e^(x). Good luck
Also, why would i need ln(x) if its just log(x)/log(e) ? As a start, i will only have base 10 log. BTW, how do i rewrite x^y as e^(x)
Because there is more information on how to implement ln(x)
To rewrite x^y as a power of e you would use the fact x = e^ln(x)
x^y = (e^ln(x))^y = e^(y*ln(x)).
