The simplest way would be to create a table where each x-value has a y-value that is the residual at the corresponding x. With a 2-list data set you can plot you residual plot.

The TI 86 has two logarithmic functions: natural logarithm **(ln) **and common (decimal) logarithms **(log)**. If you need the logarithm in any other base than e or 10 you need to use one of the two equivalent expressions

**log_b(x) =ln(x)/ln(b) =log(x)/log(b)**

Here b is the value of the base of the logarithm and x is the argument (the value whose logarithm you are seeking). Of course the argument x must be a positive number.

**Note:** On the TI 86 the log function can calculate the logarithm of a complex number, according to the manual.

Press and release the 2nd key, then press and release the up-arrow key to increase the contrast or the down-arrow key to decrease the contrast.

Try adjusting the contrast. It may be too dark. Turn the calculator on press the 2nd key and the down arrow. This is how to adjust the contrast and will lighten the screen. You can darken the screen the same way, but use the up arrow instead.

The software for your calculator may need to be updated. You can get the update from the manufacture's website under the download or support tab.

Sorry, but the fx-115ES can only display square roots in radical form. Cube roots are beyond its symbolic capabilities and will always be in decimal form.

That depends on how simple a calculator. I'll give some examples below for calculating the cube root of 8.

On a TI-86, press 3 2nd [MATH] F5 MORE F4 8 ENTER

If the calculator has a "^" or "y^x" key, raise 8 to the 1/3 power. Again, on the TI-86, press 8 ^ ( 1 / 3 ) ENTER

If the calculator has a logarithm key, take the logarithm, divide it by three, then take the antilogarithm. Again, on the TI-86, press 2nd [e^x] ( ln 8 / 3 ) ENTER

On a slide rule, place the hairline over the number on the K scale and read the cube root on the D scale.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so as to appear not to be turning on. Turn the calculator on (or at least press the ON button). Press and release the 2nd button, then press and release the up-arrow button. Repeat the process several times and see whether the screen darkens.
