How do you find the EXACT value of an inverse trigonometric function? What's the EXACT value of arccos(3/5), for example?

Newton method

Pretty sure it's irrational.

It is exactly arccos(3/5).

To how many apples does that number correspond? Because number exists if and only if it can describe set of apples.

this, fucking kill yourself OP
anyone who disagrees with me obviously is a brainlet

Arccos(3/5) apples

>>8824327
what about oranges?
>>
>>8824786
They too exist iff there is one to one correspondence between them and apples.

Arccos(3/5) oranges

>>8826105
Do correspondences exist?

>>8823040
The exact value is arccos(3/5). Anything else is a decimal approximation.

We're not talking about apples, we're talking about ratios.
