Good day,
I was born in the 90s and as you know, having calculators back then was a cool thing; like having the Game Boy, SNES or the Genesis. I was very fond of calculators and I still am and from time to time check out what's new on the market. To say the truth, I still use may CASIO FX-115 to...
i don't know whether this goes here or under the calculator forum. i want to graph x=t y=1/(1+t^2) and z=t^2 and i keep getting a parabola. is that right because the drawing in my book is like a slanted parabola.

Here's a graph of displacement it wants me to make: http://s15.postimg.org/7v1x5najv/graph.png. I tried that graph in the picture as the answer but it didn't accept it. There are no numbers or specifics for Figure 1 they give you, so I'm confused on what to do. Very strange...

Here is the solution to the problem, all you need to look at is the diagram, the conductivity values and the graph.
What I don't get is why the temperature is not continuous when the material changes. Shouldn't there be equilibrium at the boundaries between the different materials?

Hey, how would I graph the plane x + 2y + 3z = 0. We were taught to find the x,y and z intercepts and then connect them resulting in the plane. In the following equation, I get the points x=0,y=0 and z =0. I can see that the intercept approach doesn't work for this question. What else can I try?

Okay the graph SHOULD look like this.
