TI-84 Calculator Gives Me the Wrong Logarithm Solution

"log(2)8" means "common logarithm of 2 multiplied by 8".

The TI-84 has three different logarithm functions.
log is the common (base-10) logarithm.
ln is the natural (base-e) logarithm.
logBASE lets you take the logarithm to any positive base.

If you want the log base 2 of 8, you want logBASE(2,8). You'll find the logBASE function in the catalog, accessible by pressing 2ND [CATALOG] ). CATALOG is the shifted function of the 0 key, the ) gets you to the Ls in the catalog.

My Ti-84 plus gives me an answer of "4E-4" when I multiply .02 times itself. How can I get it to show me the decimal answer instead of the E

Unfortunately, you can't. From the manual:

If [...] the answer cannot display in 10 digits (or the absolute value is less than 0.001), the TI-84Plus expresses the answer in scientifc notation.

Im pressing in 2e^(2) and i get the answer 14.7781122 when it is suppose to be 4? What is wrong with my TI-84 Silver Edition?

Nothing is wrong w/ the calculator, e is the base for natural logarithms, therefore, you are getting the correct solution for the problem you typed. to get four, simply type 2 then the "squared" button (the button w/ a small 2 on it) and voila!

Wrong trig ratio

Your calculator is set in radians. Press mode key. Arrow down to 3rd line. Highlight degree and press enter. Your calculator is now in degrees, not radians. To get out of the mode screen and back to home screen, press 2nd and then mode.
