Go to www.wolframalpha.com/ and just type in whatever it is you want to help get solved. It's extremely useful and it doesn't cost you anything. But if that's not working out for you, then maybe I could help although I've only taken two years of calculus and it's been a while since I've done it. Just message me and I'll try to get back to you ASAP! Okay, hope this helps :)
