What’s the best way to calculate it by hand?
I’m brushing up my math basics (I graduated CS while dodging the math requirements) and it frustrates me that in trig I need to remember values at all. The values such as sqrt(2)/2 make sense but how hard is it to calculate sin(5 degrees) by hand?
- _v7gu 3y agoFive is small enough that you can get away with sin(5 deg) = 5pi/180
- HenryPrickett 3y agoUse a Taylor series with a four function calculator. 0 is a decent approximation of sin near 0. x is a better one. x - x^3/6 is an even better one. x - x^3/6 + x^5/120 ... Note that x here is in radians rather than degrees so convert (degrees * pi/180) first. Repeat until you're satisfied with how many stable digits you get
