If you're worried about integration, you can use your calculator to double check all your answers. It only works for definite integrals though.
So for example if you want to find the integral ∫x2cosx between 10 and 30
you press the ∫dx button on the calculator top left next to "CALC"
then type in the function
to type in X just press Alpha and then the ")" button
then "^" button, then "2"
followed by "cos" and then Alpha ")" to get the x
finally to specify what region press the "," button it's next to the ")" button
then enter your starting point "10" then "," again and then your ending point "30" and finally close the bracket by pressing ")"
and press equals and it spits out an answer for you
depending on how complex the integral is, it can take a really long time, i remember once it took 8 minutes to just calculate one integral
Edit: it should be x^2 not x2 at the top
