Differentiation of integrals and integration(?)

Click For Summary
SUMMARY

The discussion centers on the application of the Leibniz integral rule, specifically the formula for differentiating integrals with variable limits. The formula is given as \(\frac{d}{dx} \int_{a(x)}^{b(x)} f(x,t) dt = f(x,b(x)) b'(x) - f(x,a(x)) a'(x) + \int_{a(x)}^{b(x)} \frac{\partial}{\partial x} f(x,t) dt\). Participants seek clarification on the types of integrals that can be evaluated using this formula and the general procedure for applying it. The conversation highlights the need for a deeper understanding of the conditions under which this rule is applicable.

I heard that the formula below can be used to evaluate some kinds of integrals but I can't find what kinds and how to do it.Could someone name those kinds and also the procedure?

[itex] \frac{d}{dx} \int_{a(x)}^{b(x)} f(x,t) dt = f(x,b(x)) b'(x) - f(x,a(x)) a'(x) + \int_{a(x)}^{b(x)} \frac{\partial}{\partial x} f(x,t) dt[/itex]


Thanks
 
Physics news on Phys.org
That doesn't contain what I wanted.
I have seen another page from wikipedia too.That one contains some integration using the formula but I can't understand the general procedure.
