Okay, so this one's kind of fun because i don't think i've actually ever done this question, but it's just kind of an algebra question.
00:11
So they're asking, maybe i should read the question first.
00:14
So we're told that we have the function f of x equal to x squared, which is our friendly parabola we all know and love.
00:27
And we're told that the area under the region, sorry, the area of the region under the curve from zero to six, some value is 100.
00:39
So maybe this is that value b, they called it, and the area here is 100.
00:45
So we're trying to find out what that value b is to get that area.
00:50
So how far out to the right do we have to go before the area under the curve is equal to 100? so basically what we know is that the area under the curve here is equal to the integral, the definite integral from zero to whatever that value is, that b value.
01:08
So we are given this equation essentially that the integral from 0 to b of x squared, oops, x squared d x is equal to 100...
