Question about Texas Instruments TI-84 Plus Calculator
Clear the you the RAM to revert to default settings and restart. I am including screen capture fro a TI to show you how to set up the calculator.
Notice the white-on-black equal signs. For a function to be drawn, the equal sign in its definition must be highlighted. To effect that you scroll left to the = and press ENTER. You will know the function has been selected for graphing if its equal sign remains white-on-black after cursor has moved to another location.
Here is what the 4 functions look like. They all are on same graph.
Now we will change the graph stythe calculator only allows one line equation to - fce7a77.jpgosine function.
The only difference between the first screen and this one is the style of the line at the left of the Y4. To change the style, you move to the cursor to the left of the Y and press ENTER. Each time you pressthe calculator only allows one line equation to - 00e0856.jpgR, the style for the function in question changes. Here is the product.
The wavy curve (cosine) is now dotted.
Hope it helps.
