Those are as follows: I have chosen the latter method for the explanation that follows. Others may, of course, have their own favorite method.

Proper fractions are entered in the usual way. The syntax for exact is as follows: The default for tolerance is invoked here.

Now suppose we want. Do it as follows: Enter information so that the expression reads as follows: The default is the common log. For logs to other bases, the syntax is log number, base. For example, to base 2 would be entered as log ,2.

The natural logarithm is on the keyboard. I usually just enter it ln 3.

The approximate intercept appears at the bottom of the screen. User are other manual on the CALC menu, including minimum, maximum, derivative, definite integral, and intersection of two graphs. Do a matrix calculation: Square matrices sometimes have inverses. To find B Find the row-reduced echelon form of A: Your home screen now says rref.

Fill in the matrix name A, close the parenthses, and evaluate: Do not confuse rref with ref. If a matrix is too large to fit completely on the home screen, use the arrow keys to see more columns or rows. Get in sequence mode: Enter a closed-form sequence: This sequence should read 3, 6, 18, 72,Table of sequence terms: Adjust table values first below!
