It helps me understand functions and other algebraic expressions that I don't understand outside of class. Especially for those freaking huge problems that take forever to type, the fact that this can be done offline just makes it more useful, specially when my data is very limited.

So I downloaded this app and I would use it on the problems I wasn't sure on, the ultimate tool for students, i've been having trouble with math homework and google has been no help so this just great. It's easy to use for most questions. The best app i have ever seen or used, would recommend to everyone no matter what stage of math they're at, although it's a bummer some features are locked behind a pay wall.

It helped me a lot in my Calculus homework and taught me how to find the solutions faster than the boring and long methods of my professors, but it is very helpful and a life saver, but This app is way too simple, incredible app. The picture aspect sucks but it helps me with like 90 percent of calculus problems.

To find the derivative, use the equation f’ (x) = [f (x + dx) – f (x)] / dx, replacing f (x + dx) and f (x) with your given function. Simplify the equation and solve for dx→0. Replace dx in
Decide math equation
To solve a math equation, you need to figure out what the equation is asking for and then use the appropriate operations to solve it.

Dividing both the sides by δx, δy / δx = u (δv / δx) + v (δu / δx) + (δu / δx)δv Taking limit as δx ⇢ 0, we get = u (dv / dx) + v (du / dx) + (du/dx) × 0 As R.H.S. exists and is equal to
