You would demand a T1-83 Graphics Calculator for this question who ever helps me out.
QUESTION:
(a)
Plot the graph of Y = cos(X) - 0.6 on your computer for X = 0 degrees to 360 degrees.
IF ANYONE CAN PASTE A SKETCH OF THIS GRAPH IT WOULD BE HELPFUL OR TELL ME WHAT TO Strain ON THE CALCULATOR)
(b)
Use the graph in part (a) and your calculator to find the two solutions of the equation cos(X) - 0.6 = 0 that lie between 0 degree and 360 degrees to the nearest point, explaining your method.....
Please help me someone? Thank you.
Thank you for the info, it has helped but still struggling to get the answer.
(a) Typewrite in the calculator the function that you have there.
Click the "Y=" button in the top left corner (it should be a different color from your other buttons) and then genus in cos(x) - 0.6. The COS function has a button all its own, and the "x" button also has a few other signs on it, but you can really use any variable you dearth.
(b) Basically, anything falling between 0 and 360 will be from the y-axis (the straight line upwards) to the start of the next cycle on your abacus. So when the arcs start to repeat, that's when you've passed 360 degrees. The two spots where the equation crosses the x-axis before the arc starts repeating are where the answers are.
Smooth "Stat Calc" (it's up there near the "Y=" button) Click on "Spot", and a little box will show up on your graph. You can move it around with the arrow buttons (right side of the calculator). Click on the spots where the letter crosses the x-axis, and it'll give you the value. You can also press "Value" when you get to Stat Calc, and perform the directions it gives you, to get a more exact value.
Hope that helps. :)

What programs or mods do you recommend I get for my TI-83+ calculator?
Aug 01, 2009 by James M | Posted in Software
I'll be in AP Calculus AB and I would like some mods/programs/hacks so I can have an restless. I saw some things on ticalc.com but there was a lot of stuff so I didn't know what to get.

Is there a calculator that will figure out witholdings for a Colorado paycheck from only the check total?
Aug 01, 2009 by Erin | Posted in United States
My corporation failed to report 2 and a half months of my employment. After dragging their feet, they now want to pay me off with what I would have received had I reported it on my tax offer. I need to report this job in order to prove residency and get financial aid. Because they will continue to drag their feet on this unpolished charade, is there a way to figure out what is commonly withheld, percentage-wise, from a Boulder, CO paycheck? I do have one pay stub, so I conscious what the business paid in to. Basically, I just need to work backwards from my paycheck totals to find out how much I paid out.

Take a look at the close-up "Detail View" image. What you are looking at is the image of the "pi" symbol, that we've all used in math class growing up...but the symbol is actually made out of the first 5000 digits of Pi. I have altered the colour only on the numbers in the middle to create the shape of the Pi symbol. The numbers read clearly starting with 3.1415....etc at the top. Each row has one hundred numbers in it, a total of 50 rows. The number of "pi" is said to go on forever. I have seen an example of over 1 million digits before.... (which would be way too long for a zazzle product!) It's a great conversation starter...even for those who aren't into math. I designed this in vector-art software for the best possible image. Look for the other Colour variations of this image, and the other products available with this design in the rest of my zazzle store!
Respect The Calculator ... Vintage Adding Machine
Soon To Be Retro, The Electronic Calculator
Now considered vintage and old fashioned computer style calculator becomes a retro artifact of the past at a fast pace. Disc Drive, floppy, cassette, tape drive, adding machines, calculators and many more high technology of the 1980 and 1990 are now only points of interest on the time line of computer evolution.

I had a Sinclair ZX Spectrum + (with a massive 48K RAM!) back in the 1980s, before I moved on to the Sinclair ZX Spectrum + 2 (with a built-in tape recorder), Commodore Amigas and PCs. The keyboard was a vast improvement on the horrid rubber keys that my old 16K ZX Spectrum had before...
