I was about to solve it happily but then noticed these funny symbols and realized i've never taken calculus

I have some issue with reading a formula:

[math]c=(2n - 1)\pi/2l[/math] which then later shows up in [math]exp(-c^2\alpha t)[/math], with n being used in [math]\sum\limits_{n=1}^\infty[/math]

How do I interpret that 2l part? As it's written, it's …pi / 2 * l, but if I use it llike that, the exponent becomes just insanely large, with the sum never converging. So …pi / (2*l) seems like the logical way, but wouldn't that strictly be wrong?

What do?

No one gives a fuck. The fact that sine and cosine have a period of [math]2\pi = \tau[/math] is more important and fundamental. Who the fuck even uses diameter in pure mathematics? Brainlets like you, that's who.

>The area of a circle is certainly more brief, and therefore more witty, if you write it as [math]\pi r^2[/math] as opposed to [math]\frac{\tau}{2}r^2[/math].

There's a reason that factor of [math]\frac{1}{2}[/math] is supposed to be there, though it's probably way beyond your comprehension. Hint: It involves this really simple concept called integration. Hence why you see [math]\frac{1}{2} m v^2, \frac{1}{2} k x^2, \frac{1}{2} I \omega^2[/math].

The area of a circular sector subtended by angle [math]\theta[/math] is [math]\frac{1}{2} \theta r^2[/math]. Thus [math]\frac{1}{2}\tau r^2[/math] is just the special case [math]\theta=\tau[/math]. [math]\frac{1}{2} \tau r^2[/math] makes this clear, unlike shitty [math]\pi r^2[/math].

tfw I can't understand half of his videos

Why do i keep getting dumber? I have a really hard time remembering names for people and names for roads. Numbers are really hard too, i don't even know my own mobile phone number.

I'm scared. I didn't used to be like this, i was regarded as the bright kid when younger.
How do i get smart again?

Oh yeah, i forgot to ask, plumber and welder, is it social? I like being with people, as silly as it may sound for someone with the 'tisms.
