Are trig tables supposed to be intuitive, or does everyone

what's a trig table, just standard trig function values?

x 0 30 45 60 90
sinx sqrt(0)/2 sqrt(1)/2 sqrt(2)/2 sqrt(3)/2 sqrt(4)/2
cosx sqrt(4)/2 sqrt(3)/2 sqrt(2)/2 sqrt(1)/2 sqrt(0)/2

The only shit you need to memorize it's what's on the unit circle. Or really just one quadrant of the unit circle, since you can just flip the appropriate signs for their multiples.

Just solve the first three or four elements of the taylor series if you don't have a calculator to do it for you ffs

its not that much to memorize really, i remember doing this years ago (i'm in Med school now).

There are 3 different values for each of the 16 possible places on the unit circle.

That's 48 total values to memorize, not that much honestly.

Have I walked into the 17th century or something?

Fuck, I still don't know this from memory. Always had it in my graphing calculator during high school and after that I barely ever needed it.

just do rational trig instead. WAY more intuitive

It's literally just counting from 1 to 4.
[math]\frac{\sqrt{1}}{2}, \frac{\sqrt{2}}{2}, \frac{\sqrt{3}}{2}, \frac{\sqrt{4}}{2}[/math]

>>8949832
All you need is the unit circle, sum and difference formula, and half angle really. You can approximate anything else accurately enough.

Draw a triangle animenigger.

lol

All you need is eulers identitety and 45 and 30 degree triangle trigonometry

>[math] \frac{\sqrt{1}}{2},\frac{\sqrt{2}}{2},\frac{\sqrt{3}}{2},\frac{\sqrt{4}}{2} [/math]
this is is the best way to memorise it tbqh. then you know cos is just the opposite way around on [0,pi/2] and tan is just the quotient formed by these two

You need product to sum, sum to product, power reduction, and Mollweide

Construct two triangles: an equilateral one with sides of two and a right one with sides of 1. That'll give you pi/6, pi/4 and pi/3. Pi and pi/2 are trivial.
