Question about Texas Instruments TI-83 Plus Calculator

Try reseting your calculator if needed, and sometimes answers can be off because the calculator sometimes is so precise you answers may be rounded.

I get the same answer. Is b wrong? When I do it in Excel I get b= -2E+06, which is -1 797 322.99 rounded to the millions, in scientific notation.

Let me know if you have any questions.

Good luck,

Paul

You can't simply enter 7x+9=30 into the calculator, there is a way to calculate what the x is but its been a few years since I've done these..

Enter the first term as (-20^2), not as -20^2. Without the parentheses the calculator interprets it as

-(20^2), which is not what you want.

Also, make sure you use the (-) key just to the right of the decimal point and not the - key.

That is the correct answer. 60 multiplied by 24 is 1440. 1400 divided by 1440 is a number slightly smaller than 1.

Are you sure the problem isn't 1440/(60*24)?

in order to give the calculator a function to graph, you will want to enter the y= window by pressing the top left most button on the calculator.
a menu similar to the one above will open, wherein you can enter an equation for the calculator to graph, such as (x^2-2). On the ti-83 itself, you can enter up to 9 equations to be graphed at once. after that, you may want to go to the window menu, where you can set the dimensions of the graphing plane in both the x row and y column. to view the graph, press the top right most button on the device.

hope that helps :)

Press MODE to enter the mode editor. Scroll to the second line and select FLOAT or a larger number of digits than the 2 it appears to be in now.

the book is wrong then because my ti gives me the same answer

Yes you can use it, here is the formula: Y= V(t+ (i/c))^(tc) V=amount put in, t=time, i=intrest rate, c= amount of times it is compounded.

you have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck

Srry my friend the ti 83 is no magnificent Ti-89. meaning: you have to solve it yourself. There is a method for graphing though. Set the equation equal to zero and then plug the stuff on the other side of the equation into a graph by pressing y= and then typing it in. Then hit graph. Wait for the graph and then hit 2nd calc and select zeros. Bring your cursor using hte arrow keys close to where the line hits the x axis and press enter and then do the same except to the right of that point and then press enter twice and it will display the y which should be the answer

There are quadratic formulas for calculators programmed in tibasic for the calc but other than that there is no way to solve it

Could you post an example or two? Without knowing what you're trying to do, it's all but impossible to tell what's wrong.
