Syntax is: [ln] 3 [EXE] gives 1.098612289 exponential of 4: [SHIFT][LN] 4 [=] 3 The inverse of decimmal logarith is raise 10 to a power. Both share tha same physical key [LOG] log of 6: [log] 6 [=] result is 0.

Antilog of 0.77: [SHIFT][LOG] 0.77 [=] result is 5.888436554 For more complicated arguments (expressions) it may be a good idea to use parentheses to enclose the arguments of functions.

Use arrow to highlight STAT and press EXE Press F5 DIST Then select F3 CHI Choose Cpd or Ccd If you choose Cpd: you must enter the Chi value you want, and press EXE, then the number of degrees of freedom (df) and press EXE. The Execute command is highlighted. This allows you to perform the actions indicated by the Thumbnails at the bottom of the screen: calculate a value or Draw the distribution. In the example above I took Chi=1, and df=3 and pressed the CALC menu. If I press the DRAW menu instead, the distribution is displayed. If you want the other distribution Ccd, press Ccd instead in screen capture 4.
