Question

exact value if a=0 and b =1
evaluate the integral: (9x^3 . (sqroot x) -2x^5 + e^-2x  +11x) dx

loser66 · Answer

$$\int_0^1 (9x^3\sqrt{x} -2x^5+e^{-2x}+11x)dx$$
is it right?

anonymous · Answer

yes

loser66 · Answer

so? what stops you work on it?

loser66 · Answer

$9x^3\sqrt{x} = 9x^3x^{1/2}= 9x^{7/2}$

anonymous · Answer

just trying to see other peoples working out. I got (23/3) -(1/2e^2)

loser66 · Answer

correct if e^2 is in denominator $\dfrac{1}{2e^2}$

To help find the velocity of particles requires the evaluation of the indenite integral of the acceleration function, a(t), i.e. v = Z $$\int\limits_{}^{} a(t) dt$$
Evaluate the following indenite integrals:
(a) $$\int\limits_{?}^{?}  \frac{ \ln t }{ t^4 } dt $$
(b) $$\int\limits_{?}^{?} (t^2 + 1) \sin9t dt$$
sorry you have been really helpful can you please show me the working out for this?
