Challenging Integrals in Calculus 1-2: Expand Your Problem-Solving . . . The discussion revolves around participants seeking and sharing challenging integrals suitable for Calculus 1-2 Users propose various integrals, including \int {\frac { (1+x^ {2})dx} { (1-x^ {2})\sqrt {1+x^ {4}}}} and \int e^ {-x^2} dx, while expressing excitement about their complexity Some participants discuss the difficulty of specific integrals, such as \int_ {0}^ {\infty} \sin (x^2) dx
What Are the Pitfalls of Multiplying and Dividing in Integration? Usually trig integrals need that, but even a simple integral like \int_ {0}^ {1} dx Can go wrong if we multiply and divide by the same thing Also most of the time we aren't just multiplying and dividing by a number, we do a variable For instance, to the above integral, if I go ahead and multiply and divide x (x x) then that integral becomes
Solving Definite Integrals with a TI-83 Plus - Physics Forums does anyone know how to solve definite integrals using a Ti-83 plus? my teacher said it's okay to use it to check your answer during a test, so if you know how, please let me know also, is it possible to do indefinite integrals using ti-83 plus calculator?
