Hi,

a 6ya Technician can help you resolve that 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 repair professionals here in the US.

click here to Talk to a Technician (only for users in the US for now) and get all the help you need.

Goodluck!

You can buy ph test strips that change color and you then compare them to a color chart. If you are intending to do a lot of testing you can buy a ph meter.

If you know the values of a, b, c, and d you can calculate a+b, and c+d. No further simplification is possible.

Assuming your two point coordinates are of the form (x1, y1) and (x2, y2).

There are two possible methods:

You can use the slope formula which is commonly known as "rise over run." To do this: slope = (y2 - y1) / (x2 - x1) This means that the vertical distance covered by the two points divided by the horizontal distance covered by the two points is equal to the slope.

You can use your calculator's linear regression capabilities:

First step: Press the STAT button (next to the arrow keys toward the top right of your calculator).

Second: Select the first option, Edit...

Third: Under L1, enter your first x value, press enter, enter your second x value, press enter again.

Fourth: Under L2, enter your first y value, press enter, enter your second y value, press enter again.

Fifth: Press the STAT button again. Press the right arrow button to highlight CALC.

Sixth: Select the fourth option LinReg(ax+b).

Seventh: Press 2ND then 1 (L1 should show up on your screen). Then press the comma button (right above the number 7). Press 2ND then 2 (L2 should show up on your screen). Press ENTER.

Eighth: Once you press ENTER, several values will appear. The a value is the slope of the two coordinates.

Once the graph is drawn you can use the Calculate menu to find

You cannot find the location of an inflexion point as this requires the knowledge of the 2nd derivative of the function, and this calculator calculates the first derivative only. However, there may be 3rd-party programs that handle this, on ticalc.org website. Use at your own risk and under your sole responsibility.

To access the seven menu options above, you press [2nd][TRACE] to open the (CALC) menu. Use the Down and Up Arrows to move cursor along the menu options.

- 1:value, the value of the function at a point
- 2:Zero, the coordinate of a point where the function vanishes (has value zero)
- 3:minimum, the location of a point where the function has a minimum
- 4:maximum
- 5:intersect , the value of the function when it crosses the y-axis (y-intercept)
- 6:dy/dx, the value of the derivative of the function at a point.
- 7: Integral (f(x),dx)

It is the [xy] key.

I hope this helps.

There is a guide online at this LINK.

the Xy button, 10 Xy 2 = 100 (10 x 10)

to do a neg exp you have two options, one use brackets if calculator has them.....

10 Xy (-2) = 0.01

or two inverse your number, ie: make 10 into 1/10th, use fraction entry on calculator.

1/10 Xy 2 = 10 Xy (-2) = 0.01

to do a neg exp you have two options, one use brackets if calculator has them.....

10 Xy (-2) = 0.01

or two inverse your number, ie: make 10 into 1/10th, use fraction entry on calculator.

1/10 Xy 2 = 10 Xy (-2) = 0.01
