The natural log of 10E4 is about 11.51. The natural log of 1E4 is about 9.21.

Do you want the log of 10 to the fourth (ten thousand) or of 10 to the fifth (one hundred thousand)? What keys are you pressing to enter the argument? If you press 1 0 2ND EE 4 then you're inputting ten times ten to the fourth or ten to the fifth. If you want ten to the fourth, enter it as 1 2ND EE 4 .

-1E-13 is a very small number. When doing this kind of a problem you can regard 1E-13 as 0.

Remember that pi is an irrational number. It is only estimated on your calculator. I just played around with a TI-83 and found the following answers:

cos(pi/2) = 0

cos(2*pi + pi/2) = 0

cos(4*pi + pi/2) = 1E-13

cos(20*pi + pi/2) = -1E-13

As you know, that correct answer to each of these is 0. The calculator gives non-zero answers because some very small errors are accumulating. There is nothing wrong with your calculator.

Isolate the integer part (to the left of the decimal point)

Convert the non integer part (decimal part) into a fraction.

Write the result as (integer part) (fraction part)

3/2=1.5

Integer part is 1, decimal part is 0.5

0.5 as a fraction is 1/2

3/2= 1 1/2

You're trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

It's the key at the top left of the keyboard, just below the five function keys, marked "2ND"
