Y plottingI am trying to plot equations where x is the independent variable, such as y=sqr (x), or y=2, and I always get empty plots. How should I proceed?
Hi, MathStudio assumes the equality 'y=f(x)' and you don't have to enter 'y=', just the function 'f(x)' that you want to plot. In your case it would be 'Plot(sqrt(x))' and 'Plot(2)'.
Thank you, Francisco . . .
Perhaps I didn't make my self clear. I am trying to plot vertical lines, horizontal parables (x=y^2), for example, or slanted lines and I get horizontal lines, vertical parables, (y=x^2) or empty plots. Please help.
Ok, now I understand what you want to do. You can do that using parametric plots, just set the function 'f(x)' of y=f(x) on the on the first entry, and 'x' on the second one, like this:
I am sorry, I definitly didn't maje my self clear. Ir is x=f(y) that I am trying to plot, not y=f(x). Thank you.
I still don't quite understand what do you exactly want, can you give an specific example, with images if possible?
Got ir, Francisco . . .
Thank you Francisco . . .
I used to work with "Fluidmath" but unfortunately IOS is no longercompatible with this App.Atached you will find an example of one model I developed with suchApp.Using "sliders" I was able to change the values of "a", for instance tochange the parable without modifying its origin. Also by changing "m" and"c" I could change the slope of the blue and black lines, respectively.Finally the purple lines would indicate the crossing of both lines (blackand blue). This model identifies the type of use I intend to give to yourApp. I can now plot both lines and they work very well with the sliders.However once the curve is plot, using ParametricPlot, every time I try toadjust the parable, the scale of the plot goes wild. Is there something Ican do to go around this.
I cannot see the attachment, can you upload it again?
I am attashing a pucture of one of muy models ti which I refered ti in muy previous message
I am sorry, I was unable to attach a picture. Perhaps if you provide me with a standard email address I Willy be able to include it.
I was a unable to atach the picture of my model and its equations using sliders. I couldn't find the way to include it in your page. If you provide me with a regular email address I will gladly be able to atach it
