Question

Someone explain this problem to me?
See below.

Answer 1

\[\int\limits_{0}^{\sqrt{\frac{ \pi }{ 2 }}} \cos(x^2)dx\]

Answer 2

This is the work they have.
what i don't get is the fourth term (cos(rad(pi/2)/4))

Answer 3

this is simpson's approximation rule right?

Answer 4

no, trapezoid rule. we were told not to use simpson's rule b/c we haven't learned it yet.

Answer 5

damn i can't write it, so i will just say it
they are increasing each time by the square root of pi over 2, over 4

Answer 6

oh i see! the fourth term is wrong
i think it is a typo actually

Answer 7

i thought so too. ok thanks.
