SUMMARY

The discussion centers on the calculation of partial derivatives fxx, fxy, and fyy for the function defined by the integral of cos(t squared) from y squared to the square root of x. Participants clarify that computing the integral is not necessary, as the Leibniz integral rule provides a method for differentiating under the integral sign. The mention of "Fresnel" indicates a potential confusion with integral calculus concepts not covered in the course. The conclusion is that students should focus on applying the Leibniz rule rather than attempting to evaluate the integral directly.

PREREQUISITES
  • Understanding of partial derivatives
  • Familiarity with the Leibniz integral rule
  • Basic knowledge of integral calculus
  • Concept of differentiating under the integral sign
NEXT STEPS
  • Study the Leibniz integral rule in detail
  • Learn about differentiating under the integral sign
  • Explore the properties of Fresnel integrals
  • Practice calculating partial derivatives for functions defined by integrals
USEFUL FOR

Students studying calculus, particularly those focusing on partial derivatives and integral calculus, as well as educators seeking to clarify the application of the Leibniz integral rule.

Homework Statement


I am to find the partial derivatives fxx, fxy, and fyy off(x,y)=
eq.latex?\int_{y^2}^{\sqrt{x}}cos(t^2)dt.gif
The integral from y squared to the square root of x of cos(t squared) dt

Homework Equations



The Attempt at a Solution



All rules of integration I know fail, and attempting to use an integral calculator leads me to a term "Fresnel", which has never before been explained in my class. This leads me to assume I'm not supposed to take the integral; how, then, do I account for sqrt(x) and y^2?
