There is, however, a big catch. I got 2 functions (exp(x)=e^x) Y1 = 2.5E-9*(exp(x/(1.75*26E-3))-1) (the Diode current I_D of a diode in relation to the diode potential u_D in Volts) X2 = 1-16Y (the characteristics I=f(U) of the rest of the circuit). Draw both. Looks splendid. G-Solv -> INTSECT > You wait. Nothing happens. After watching the videos who told me what I did was EXACTLY how I could get the intersection, I noticed that when it works, both graphs have the same type. IN THIS CASE, i=f(u) can be easily converted into u=f(i), as Ohm's law U/IR=1 allows it: y[A]=(1-x)/16\Omega So, Y3 = frac{1-x}{16} DRAW. Y3 fully covers X2, as it should. G-SOLV->INTSECT Schnittpunkt X=0.7175422867 Y= 0.0176536072 So this, unfortunately, only works with graphs of the same type (albeit X= and Y= SHOULD be possible, as it's just two different pairings of an independent to a dependent variable in the xy-plane). MORE UNFORTUNATELY, Casis didn't implement any error message. A simple "Error: Type mismatch" would have sufficed to save me a lot of research.
@@TheCalculatorGuide there definitely is. I sat my GCSE exam this year and you would be instantly disqualified if you brought a calculator capable of graphing into it.
@@AnKot Which GCSE exam...was it Cambridge for the international GCSE? I know previously the didn't allow graphics although I am not sure if that has changed. For the regular GCSE here in the UK there is no restriction on graphic calculator use.
It depends on what type of graph you have setup for. Try pressing F3 (TYPE) and F1 (Y=) and then press. See if this gives you x instead for these graphs.
From the manual its says the following " Invalid Type: An illegal data type is specified - Specify valid data" Are you using any data or lists in you graph? Have you got it set to Y = and not r= or Xt = on your graph entry?
*Sorry about the calculator disappearing at **2:17**, not quite sure what happened there!*
lol thanks for making the vid

I got 99 out of 100 in maths by watching these calculator videos!!!!!
@D S you cant take this into a GCSE exam
No rule against taking it in at all.

@@TheCalculatorGuide I sat the new GCSE maths 9-1 exam in the UK and the only allowed calculator was the classic Casio one.
instead of my calculator saying graph func Y its says dynamic func Y how do I fix this ?
there are not any numbers in the x and y axis in my graph how can i get that.
Make sure you have the TYPE of graph by pressing F3 and select option one with F1
When I type in the x button, I get T instead so I get an error when I want to draw the graph?
It depends on what type of graph you have setup for. Try pressing F3 (TYPE) and F1 (Y=) and then press. See if this gives you x instead for these graphs.
I want to know how to add picture in calculator , I can't do it
Yes, I think you can put a picture behind the graph. I will look into doing a video.
My y-intsect doesn't work!
I keep getting Invalid Type Press: EXIT, whenever I press draw. Why is that??
From the manual its says the following " Invalid Type: An illegal data type is specified - Specify valid data" Are you using any data or lists in you graph? Have you got it set to Y = and not r= or Xt = on your graph entry?
How do I draw hyperbolic function graphs on this calculator
You can access the hyperbolic functions in graph mode by pressing OPTN and then HYPERBL. You can use them from there.
