To go from velocity to position, we need to ....

anonymous · Answer

integrate

Can you integrate the velocity equation?

liizzyliizz · Answer

yeah that i can do.

anonymous · Answer

You can?  I can't.... 
$$\int \sin(t^2)dt $$
can't be expressed in terms of elementary functions.  Unless you are allowed to use some numerical integration software, I'm not sure how you can do much better than a good estimate.

dumbcow · Answer

the indefinite integral of sin(t^2) is not defined using elementary functions however you can approximate the definite integral from 6 to 7 $$\int\limits_{6}^{7}v(t) = x(7) - x(6)$$ x(6) = 4 $$x(7) = 4+ \int\limits\limits_{6}^{7}v(t)$$ For the integral --> http://www.wolframalpha.com/input/?i=integrate+5sin%28x%5E2%29+dx+from+6+to+7

when  i meant i could, i meant i could use the calculator to do what ^ did. lol. but my answers were coming out odd. :/
