  • @BeastlySin ty :)

  • @TheBlazeofRazgriz thx :)

  • @pearlwhite21 because pi/12 is a coefficient and not a constant standing alone. it is like if you are taking the derivative of 2x^2 you get 4x. so in essence the pi/12 and the 2 are the same thing.

  • @pearlwhite21 the pi/12 came from the derivative of 1/3pi(h/2)^2

  • why do u keep pi/12 when u get the derivative? why doesn't it turn to 0?

  • i fucking love you
