I would love to give this 5 stars but for the love of all that is good why did they choose to index lists, arrays, matrices etc. starting from 1 instead of zero??

This is a fantastic app! As someone who is versed in Mathematica and MatLab I find your interface and syntax to be just about perfect. I do have a few feature requests though: - One thing I need though which seems to be missing is the ability to shade below a graph to the x-axis but only between two given x-values. - I would like to have the ability to print all results in decimal only. - I would be great if “shift”+”enter” would creat a new line for a multi-line command.

I enjoy the ease of use and ui. I also like the purple colour scheme. My main complaints are things that I think people looking for a powerful mobile math program are likely to be frustrated by: 3D graphing of vectors: only one quadrant is displayed, the coordinate system is unable to be changed, and the zero vector coordinate is not actually in a consistent position. Their 3Dvector plot function does not even work on the website version, so it is not a question of my misuse. Roots of odd numbered powers: the graphing of these roots seems to fail to display the negative outputs values, thus annoyingly not presenting the full graph. Stability is also not terrific. All in all, I like the software for simpler things like algebraic expansion and the solving of polynomials, but would be able to love the app if I were able and I effectively graph 3D vectors in a way that doesnt have an abysmal coordinate system.

Please try: Plot((1+(cos(1/x))^2)^x) Limit((1+(cos(1/x))^2)^x,x,0) The result are different !? Please update and fix this problem.

For $20, I would expect much more from the app. While the concept is there, the delivery is subpar with regard to documentation being clunky and the UI being sparse. Example: try to search derivative in the manual... it won’t show up. But if you search Calculus, you can find derivatives. For a math app, the UI being sparse is good for many reasons, but where it becomes a glaring problem is the math input. There needs to be a “pretty math” input similar to the the TI NSpire where you can easily see your complex equation in standard form rather than just a complex line of parenthesis and carrot symbols. When dealing with multiple polynomial fractions in a single calculation, this will get ugly very quickly. Also, when I try to do a define via := logic, the entire app crashes and closes.

Right after my purchases I did some trials in error using the application unfortunately not able to comprehend its purposed rover me to a conclusion to look in the applications website for manual information and what is new in 2020. - I needed to learn how the application works before trying to do my homework.

I’ve been using this app since it was SpaceTime. It is very flexible and fast. I have encountered the occasional minor issue that I have been able to resolve via the discussion group. ** it appears that the discussion group is no longer accessible via Safari.

The default iOS keyboard is not efficient for this type of application... it's a major drawback. Take as an example the numeric pad in excel iOS for a much better experience.

Great app, but can you please fix issue with app crashing when trying to save image of plot

I will say that if you are looking for a basic calculator, look elsewhere. If you are looking for a math tool then this is the app for you. This app has a small learning curve that can be achieved by going thorough the What’s New example file. Once you understand the syntax this will be your go to app!
