Example 2:
This Thing does Trig!
Super COOL!

4. Fractions Reducing and Dividing: Reduce: Divide/ Decompose: #3 expand(
#7 propFrac(

5. Fractions
[F2] - Algebra Menu
Adding and Subtracting: #6 comDenom(

6. Cool! [F2] - Algebra Menu #2:factor( ) over the Integers
#2:factor( , x ) over the Real #’s
over the Complex #’s
#A: Complex 2:cFactor( )
Edit to:
Cool!

7. 1: solve( , variable)
8: nSolve( , variable)
A: Complex
1:cSolve( , variable)

#3: expand(
#9: Trig :tExpand(
COOL!
WAY COOL!

9. Trig. REM: Three answer forms: (a) principal answer
(b) all answers in [0,2]
c) all answers << +2k>>
Careful…..remember multiple answers!

10. Trig. solve( ,x) returns a weird answer @n# = k 2k n [1,255]
if only one let n=0
Careful…..remember multiple answers!

11. Trig. @n# = k if more than one let k1=1 & k2 =2
Careful…..remember multiple answers!
