[BlindMath] Getting math graphs to college professor?

[Bill Dengler]

In terms of showing graphs from the calculator, could you not just specify the equation of the function (in an algebraic sense) and the bounds over which you're referring?
For my math coursework, we’re generally asked to draw graphs by hand, without reference to a calculator, to show understanding of a function’s behavior. For this, I generally ask about the underlying concept (as drawing a graph is not generally the skill being assessed, but rather things like identifying intercepts/asymptotic behavior/concavity/extrema, the amplitude/period/behavior of trigonometric graphs, etc) and, through an agreement with the teacher/lecturer, write a description like the following in place of a graph:

The function decreases from $-\infty$ to a local minimum at $(3, -27)$. It then increases from $x=3$ to $\infty$.

Concavity description: The function is concave up from $-\infty$ to an inflection point at the origin $(0, 0)$. It is then concave down until another inflection point at $(2, -16)$, at which it continues concave up to $\infty$.

You and those teaching you should be able to come to a similar agreement – but as with anything else, different teachers will demand different levels of specificity in your description, and you’ll need to adjust accordingly.

Hope this helped,
Bill

> I’m taking college algebra and I’m runing into a lot of homework problems that require graphs done either by hand or shown on a graphing calculator. I have a Dell P.C. laptop computer, a Polaris Braille Sense, an iPhone SE and a Orien TI84 graphic calculator. My teacher and I are scratching our heads on today’s query. How do I get graphs that I make on my TI 84 calculator to my teacher? I know that there are also other ways to make the same graphs. Does anyone know of any other alternitive ways to get graphs to my math teacher? I have heard that the Polaris Math app can do this but believe it or not, that feature is so new that I have not been able to find much information on learning how to use the Polaris Math app. Because of this, I’m suposed to get training on this feature. Because I need to be able to do this ability now, what are ways I can do this today, before I can start my Polaris Braille Sense training? Can I get free accessible apps for JAWS or NVDA to cover this big gap in my technical skill set? I have the Orien TI84 which is where I currently make my graphs. But, I dofn’t know how to get them to my computer. I have the link to the correct software which is awesome! However, will I need anything else such as a special cable to go along with this program? I have not had a lot of help in this department lately and I would really appriciate you guys to come through this time. Just to let you all know, the resources out there are not enough for my current technical needs. Because of this, I need feedback on this issue ASAP. Thank you!!!
