Cosine values are between -1 and 1. The arcosine domain is between -1 and 1. The value you have is out of range.

Square root of (y^5)

Question?

Read about the nature of the cursor. It can be on Insert or overwrite. If the cursor is full square and flashing, that mean the memory register for the input line is full and you cannot input anymore strokes.

You may be making a confusion between intercepts and intersections. Intercepts are crossing of the axes. Intersections are between two curves: You need to have two curves graphed. You choose the first curve by selecting it (Up or Down Key), and then the second one.

If either error occurs when trying to graph a function (not a STAT PLOT), the error can be corrected by turning off the STAT PLOTS. The following steps will turn the STAT PLOTS off, allowing the graph of the function to be displayed.• Press [2nd] [Y=] to access the STAT PLOTS menu. • Select 4: PlotsOff. • Press [ENTER]. • Try graphing a function like y = x^4-3x^3+6x-1

Wow. Just wow. How did that person do that?! Anyways, try resetting ALL of the memory, and see if that helps, if not, ask the student what she did so that it can be reversed (probably by doing the same steps in the opposite order.

Ok, try these two things and you should be just fine.
1.) Check your range for your graph. It is possible that the range you are using isnt large enough to show the curve. Also try using Z-fit vs Z-st. These are options that your calculator will give you once the equation is graphed.
2.) Place a parenthesis around the 2x, make sure that you and the calculator are both using the same order of operations. This move mill ensure that the calculator will multiply the variable, x, by two and then do the exponential.
This should do it!
Happy Graphing!

looking at the buutons, it is at the far left, 5th down it says x2 put the number before it then click that button and then it should square

When the radicand is completed, use the right arrow to leave the root so that you can enter the other factors or terms.

Play with the display contrast to darken it. Press 2nd key and release it Press UpArrow and hold pressure until you get something on screen. Up and Down Arrow keys allow the control of the contrast.

If you have the latest OS, press the ALPHA key then use the F1 and select 2 Un/d

On the x-axis (horizontal axis) represent the time variable. On the y-axis (vertical axis) represent the temperature.

If your equation can be written in the form of a function (y=f(x)), the slope of the function at a point is the derivative of the function at the point. For any function that is not a constant or linear, you need calculus to find the slope. If the function is of the form y= ax +b, the slope is the value a.

The second button may have different markings: 2ndF, or Shift, very rarely INV

The transform application is still in memory. Press APP, then Transform. Choose Uninstall.

Factor both the numerator and denominator, and then divide both the numerator and denominator by the greatest common factor. For example, 1/3 + 1/6 = 2/6 + 1/6 = 3/6. We have to simplify 3/6. The factors of 3 are 3 and 1. The factors of 6 and 1, 2, 3, and 6. The greatest common factor is 3. Dividing the numerator and denominator by 3 results in 1/2. Good luck. Paul
