How do I preform the functions of sin, cos and tan without a calculator?

...

Here's another comfy "by hand" table for EE calculations. It was used back when calculators weren't readily available in field work.

They are ratios. They can be calculated. Calculating them for precise angles is tedious That's why That's why Icharus invented calculators. But he calculated too close to infinity and alas his calculator made of wax and bird feathers erred him into an imaginary number.

Have you got a reference?

Functions of sin are known to be easier than those others without a calculator. All you need is to place candles in the shape of a pentagram and have massive orgies around them. While this is happening, place a paper with the angle you want to find the sin of in the center of the pentagram, and wait for tue full moon. As the full moon hits, everybody will simultaneously and instantaneously climax, and the combined energy will convert the paper into the answer which you seek.

Good luck friend

this is how calculators do trig computations, but it's very difficult for us to do that in our heads

think i'm wrong? do sin(2pi/5) using 2 iterations of cordic and show your work

Nah bro satan is responding at the moment anyone have hi no. ?

>boomers think they're superior because they used shit like this instead of muh computers

In Statistics, we used something just like that for the normal distribution because even calculators today are too retarded to compute a fucking integral.

I just want to know what process the computer is doing to achieve this
