I bet you guys don't know why pic related is wrong.

π can equal 3 or equal 4 or any number in between, depending on how you measure

but π is always a number greater than 3 and less than 4

literally I just hand drawed pic related

If there is a minimum length, pi=4.

Well, enjoy manipulating symbols and crunching numbers without understanding, which is pretty much all the calculus they teach you in high school is. What's the point of memorizing all those integrals and integration techniques when wolfram alpha can do it for you these days.

If it's utility you're after, numerical methods is way more useful than "non-rigorous" calculus. But OP asked for how to go about learning pure math.

It all goes back to the fact that limits in mathematics are poorly defined.

Why isn't pi equal to 4 /sci/? What's wrong with this proof?

bang

in general, you must watch out with such constructions. E.g. the points in pic related converge closed to the circle given by x^2+y^2=1, but the length of the line segments stays invariant at 4.

Prove that pi doesn't equal 4.

Why does this work?

Yes, and this is why pi equals 4.

How exactly do you disprove this pic?

Explain this!

troll pi

Can yu explain this?
