chychochycho,ive a q,how did the ancient greeks do this without a calculator,how did they find the cosign inverse of sumtin?

[chychochycho]

I'm not sure how they did all of them, but i'm pretty sure they used special triangles for some, 30-60-90 and 45-45-90.

I'll talk a lot more about these later. Have to build up to it :)

[jamele4]

why did you round 41.4 why is it not 41.39 and y didnt you do that to 48.6

[chychochycho]

Just to stay consistent with the sig-figs that were in the question.

[jamele4]

@chychochycho ok thanx

[mixolidianmode]

4:22 i want to solve that manually without the calculator

[chychochycho]

that's not easily done without a calculator.

[mixolidianmode]

i solved for w right away using the Pythagorean theorem, is that ok?

[chychochycho]

for sure if the Pythagorean theorem works
