13-24 Using mathematical functions

4. Copy the result and

evaluate.

Thus, substituting X for S1, it can be seen that:

This result is derived from substituting X=S1 and X=0 into

the original expression found in step 1. However,

substituting X=0 will not always evaluate to zero and may

result in an unwanted constant.

To see this, consider:

The ‘extra’ constant of

32/5 results from the

substitution of into

(x –2)

/5, and should be

disregarded if an

indefinite integral is

required.

Program constants and physical constants

When you press , three menus of functions and

constants become available:

• the math functions menu (which appears by default)

• the program constants menu, and

• the physical constants menu.

The math functions menu is described extensively earlier

in this chapter.
