and

$\displaystyle \int_{0}^{t} bx^z dx=\frac {bt^{z+1}}{{z+1}}$

will the answer be :

$\displaystyle \int_{0}^{t}ax^n+bx^{n-1}dx=\int_{0}^{t}ax^ndx+\int_{0}^{t}bx^{n-1}dx=\frac{at^{n+1}}{n+1}+\frac{bt^n}{n}$

And, hopefully this would be true:

$\displaystyle \int_{0}^{t}ax^n+bx^{n-1}+cx^{n-2} \cdots dx dx=$

$\displaystyle \int_{0}^{t}ax^n+\int_{0}^{t}bx^{n-1}+\int_{0}^{t}cx^{n-2} \cdots +\int_{0}^{t}(dx)dx=$

$\displaystyle \frac{at^{n+1}}{n+1}+\frac{bt^n}{n}+\frac{ct^n-1} {n-1} \cdots +dt$

right?

>.> I hope this makes sense because i always get in trouble when mods don't understand my stuff (all through my falt of course... but still)

and I tried wolffram, I could not get it to work.

edit:

(sry for dble posting ...)

double edit: general.... thanks, does that mean there is something wrong with the equation above?
