How would I find complex intersections without the intersection function on the calculator.
Say I have y=4xe^(-x^2) and y = |x|. How would I find this intersection.
Note. I really only need the x values because I am trying to then find the area between these two curves.
Thanks. One more question. I have not had to find intersections in a long time. What if I had something simple like
seems I forgot how to find the roots when I have a power higher than 2.
If not, then you will need to use "Ferrari's cubic formula" that ADARSH links to.
