A graphing calculator (also graphics calculator or graphic display calculator) is a handheld computer that is capable of plotting graphs, solving simultaneous equations, and performing other tasks with variables. Most popular graphing calculators are also programmable and therefore considered to be programmable calculators, allowing the user to create customized programs, typically for scientific, engineering and education applications. Because they have large displays in comparison to standard four-operation handheld calculators, graphing calculators also typically display several lines of text and calculations at the same time.
Good afternoon,
I have a question on graphing this problem. There seems to be something weird going on.
In Excel, I set up the potential energy function (kx²/2) and plotted it from x = -0.300m to 0.300m, which looks like the following:
The overall shape of the graph looks like what's...

My question is when I start to graph sin (2x+6) I convert the expression to sin 2(x+3).

Hey all. This is about Ohm's Law (and specifically resistance). When you plot the change in current vs the change in voltage you should get a linear trend line (providing it is from an ohmic device). The gradient should be the resistance. My questions is why does the gradient value need to be...
I think the solution should be:
METHOD #1:

The equation I'm trying to graph on desmos is this with A & B as numbers, but I'm unsure how as it is a vector.

So I attempted this problem and to satisfy the first condition (for t in the range of [1, 5]), I drew the straight line that has a slope of 5 (i.e. f(x)=5x). I just don't understand how I can have the same function with a different slope (average rate of change) for the interval [1,10] or for [2...

When you graph something like ##θ=\frac{π}{4}## on a Polar Coordinate System:
Why does the line go into the opposite quadrant as well?
I can intuitively understand why it is in the first quadrant: ##θ = 45°## there and so all possible values of ##r## would apply there, giving you a straight line...

it’s been a while since I’ve learned basic graphing in math. I feel like whenever I graph something, it’s sloppy and probably doesn’t follow the proper conventions.

I only know how to solve this problem using graphing. I'm not sure how to do it algebraically. Please help.
Hello Forum,
I've gone about graphing the below equation by inserting values in for y and then solving for x:
y(x-1)=x2-1
For instance, I say y=3 and then solve:
3(x-1)=x2-1
3x-3=x2-1
3x=x2-1+3
3x=x2+2
0=x2-3x+2
0=(x-1)(x-2)
Thus x = 1 and 2 and so I plot co-ordinates (1,3)...
