Pi as in how can I find out the actual digits of pi if I never know it. Like how can I find out the ratio of the circle's Circumference to it's diameter
I was wondering, how can I derive pi without fancy math (fancy meaning too complex. I'm not taking out calculus or trig or anything, just not too advance concepts). Can anyone help me out?
This is I think a really dumb question, but I never got it, why do we have that dot symbol when we integrate. Like in gauss's law, we have ∫E⋅dA . why is that ⋅ there?
Thank you for your help
