Limit of an integral calculator

Thank God that I was recommended this app, the minute I tried this app I learned so much and I'm making an A in Math now, i love that I can take a picture of my problem and it will still solve it. Its funny too because my teacher hates math app but idc, works better than expected. Haven't done this math in 35 years.

Love it! I'm in college now and struggling with the new distance learning experience but with the application app I can get a different approach to the work. Which is the best part, because it's teaching you while guiding you to the answer.
