# What features could we add to Socratic that would make answering math questions easier?

##### 8 Answers

- Ability to graph multiple equations
- Ability to do solid and dotted lines
- Ability to plot points or show zeros on that graph

Ability to add a number line / sign chart

Ability to add simple shapes, ie: triangle with labeled side lengths

My problem is not knowing what is available.

I only very recently discovered "cancel", and "color" and how to set up a matrix.

I'd like tabs and tables (I currently use matrices for this) to clarify presentation (but maybe they are already there; I just don't know).

I think there should be a

- math symbol keyboard
- a mini calculator

The ability to graph functions that are defined piecewise.

for example:

Ability to restrict the domain of a function when graphing it.

I have (finally) a work-around, but it's clunky:

y=3x(sqrt(1-(x-1)^2))/(sqrt(1-(x-1)^2)) will graoh as

graph{y=3x(sqrt(1-(x-1)^2))/(sqrt(1-(x-1)^2)) [-13.57, 22.48, -4.85, 13.17]}

I suggest adding more symbols and mathematical notations to the already excellent page *Writing Math * for it to become an almost complete reference document.

For instance, symbols like the combinatorics notation
