Question

Rusty on integrating--please help--always MEDAL

Answer 1

is this
\[ \int_0^h y \frac{b}{h}( h-y) \ dy \]?

Answer 2

if so, write it as
\[ \frac{b}{h} \int_0^h hy -y^2 dy \]
and integrate term by term using the "power rule"
\[ \int x^n \ dx = \frac{1}{n+1} x^{n+1} \]

Answer 3

I don't get how the answer is
(1/6)b(h^2)

Answer 4

can u integrate this?
\[\frac{b}{h} \int\limits_0^h hy -y^2 dy\]
