Moved from technical section, so missing the homework template. You really cannot get any further without having a specific integral to do. The integral of cos(x^2) cannot be expressed in terms of elementary functions, but specific values can be evaluated, such as the definite integral from 0 to infinity, which equals.

(i), (ii) & (iii) sanitykey nov 9, 2006 integrating I noticed that if i integrate 2 \\pi r i get \\int 2 \\pi r dr=\\pi r^2 i figured its because the area of a circle can be seen as the sum of circumference's of circles with radius 0 to radius r i was thinking. Note that such a problem should be posted in the homework.
Homework statement i need to integrate an expression of the form e^ {ax^ {2}+bx+c} homework equations i know that.
The integral is proposed to equal the discussion involves using the representation of the arcsine function and applying fubini's theorem to interchange the order of integration, allowing for a. In these cases, you can simply integrate that function. How do you integrate this? The integral of 2^x can be solved using the relationship between derivatives and integrals.
$$\int \frac {1} {x^2 + 2} dx$$ my attempt is $$\ln.
