Good app, but it use vertical (portrait) camera orientation only, i use this to double check my work and it's come in handy with helping fix where I make mistakes. This is very helpful, gives u solutions for free and not many ads! It gives great step by step help too.

Good for Homework. I have no doubt that many other will say the same as me, because this app is the best. I am using it because I went on a trip and missed 10 pages of math.

Mad respect for it being free and helping me out in class, the app has been great ðŸ¥€teaches us how to do any sum you are struggling with step by stepðŸ”¥its actually easy methods that they use so that we can understand how to deal with that type of sum we encounter,you just need to focus and follow with understanding ðŸ’ši would also recommend that the app do keep our history of sums for us so that when we have forgotten the method we just go to our history box instead of retyping the whole sum againðŸ¥ºits tiring really but besides that im a happy user.

## Definite integral of rational function (video)

Letâ€™s take a final look at the following integral. âˆ« 2 0 x2+1dx âˆ« 0 2 x 2 + 1 d x Both of the following are anti-derivatives of the integrand. F (x) = 1 3 x3 +x and F (x) = 1 3x3 +x âˆ’ 18 31 F ( x) = 1 3 x 3 + x and F ( x) = 1 3 x 3 + x âˆ’ 18

## Calculus 1 : How to find integral expressions

Using the Rules of Integration we find that âˆ«2x dx = x2 + C. Now calculate that at 1, and 2: At x=1: âˆ« 2x dx = 12 + C. At x=2: âˆ« 2x dx = 22 + C. Subtract: (2 2 + C) âˆ’ (1 2 + C) 2 2 + C âˆ’ 1 2 âˆ’ C. 4 âˆ’ 1 + C âˆ’ C = 3. And C gets cancelled out so with
