Question about Texas Instruments TI-89 Calculator

Ad

I am not sure I understand but I will try. Do you want to generate a table of values for a surface you have graphed? If I guessed right then I am sorry to inform you that the TABLE is not available in 3D. I have just tried to generate a table for the surface z1=(x^3*y-y^3*x)/390 )an example from the manual). When I pressed [Diamond][Table] I got the message reported earlier.

Hi there,

Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.

Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

Here's a link to this great service

Good luck!

Add a graph .

In Documents Toolbox, select 3: Graph/Entry Edit

Unfold the menu and select Equation (not function). Enter your equation.

For the 3D part, I am afraid you will have to read the manual.

Both equations are straight lines with different slopes and different intercepts. Where these two lines cross is the ordered pair (x,y) required. This point is (0.15, 0.115)

Your calculator cannot, natively, perform 3D graphing.

**No solutions:**The system is incoherent, incompatible Example: 2x+3y=8 and 2x+3y= 15. The two lines are parallel and distinct.**One solution:**There exits a pair of values (x,y) that satisfy both linear equations. The two lines on a Cartesian graph have one intersection point.**Infinite number of solutions:**The two equations are one and the same (one is just multiplied by some constant). The graph of the two lines yields the same line. One is superposed on the other. Any ordered pair (x,y) that satify one equation (there is an infinity of such pairs) satisfies the other.**Two solutions: cannot happen**because the two lines can either intersect once, be parallel, or superposed one on the other.

Not with that calculator. You can use Wolfram Alpha to solve most equations very quickly: http://www.wolframalpha.com/input/?i=x^2+-+3x+-+4+%3D+0

You can even use it to solve systems of equations: http://www.wolframalpha.com/input/?i=2x+%2B+3y+%3D+5%2C+4x+-+3y+%3D+1

Enjoy.

6x- 3 = y; (0, -3)

Here 6x - 3 = y is the equation

The ordered pair is (0, -3 )

It means if you substitutes 0 for x and -3 for y the equation will be true

Let us substitute and see:-

'6x' (means 6 times x) means 6 times 0 which is equal to 0

So the equation 6x - 3 = y becomes

0- 3 = -3 is correct

The ordered pair means the values of x and y which make the equation correct

Hope this is clear enough

Good luck

2y - x = 3

x = 3y - 5

Add the two equations side by side,

2y - x + x = 3 + 3y - 5

2y = 3y - 2

y = 2

Plug this in the second equation to get x,

x = 3(2) - 5

x = 1

So the solution is**x = 1**, **y = 2**

or in ordered pair notation**(1, 2)**

x = 3y - 5

Add the two equations side by side,

2y - x + x = 3 + 3y - 5

2y = 3y - 2

y = 2

Plug this in the second equation to get x,

x = 3(2) - 5

x = 1

So the solution is

or in ordered pair notation
