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.
I'm trying to graph two equations to compare the two visually. For some reason, one of them isn't showing up, even though I'm in a range to where it should be. See the screenshot below.
The "3x - y = 4" is graphing fine, but for some reason, "x + y + z = 5" isn't showing up. At first, I...
I resolved the numerator to ## cosx-sinx##
We get $$mod\frac{cosx-sinx} {3(cosx+sinx)} $$
If we divide the numerator and denominator by cosx we get
$$mod\frac{1-tanx} {3(1+tanx)}$$(eq1)
We know that tan(π/4-x) is same as ##\frac{1-tanx} {1+tanx}##
So re writing eq1 we get
$$mod\frac{tan(π/4-x}...

When you graph something like ##θ=\frac{π}{4}## on a Polar Coordinate System:

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)...
