1. ## Ti-nspire graphing quesion

Does anyone know how to graph a x= function on the Ti-nspire CAS calculator. An example would be x=5. I cant seem to figure it out. Also i dont want to rearrange the equation or anything like that. Also Does anyone know if the Ti-nspire or Casio classpad can find integrals along the y-axis in graph mode.
Thx

Change into parametric mode. Then

xt1=5
yt1=t

But unfortunately you can't use parametric mode and function mode simultaneously.

Is there any other way. What if i want to do $x=y^2$. I know you can rearrange it to $y=\sqrt{x}$ but it only covers y>0 and i dont want to do that every time

To draw the graph of $x=y^2$ stay in parametric mode. Use:

x = t^2
y = t

Then you'll get both "branches" of the parabola.

5. You can plot $x=y^2$ by plotting the functions $y=\sqrt{x}$ and $y=-\sqrt{x}$ on same graph.

If you want to draw x=5, the best thing is to draw parametric equation.

Regards.

On the TI-Nspire/CAS, you can use both modes at the same time. Screenshot below:
