RE: HP Prime: CAS Commands in Home Mode
Hi,

To elaborate on the RPN syntax for calling CAS commands from HOME:

1. Simplify

“simplify(4*atan(1/5)-atan(1/239))” [ENTER] CAS [ENTER] returns 1/4*pi

2. Expand

a) If you use ‘X’ (uppercase):

“expand(‘(X+3)^2’)” [ENTER] CAS [ENTER] returns X^2+6*X+9

b) if not:

“expand((x+3)^2)” [ENTER] CAS [ENTER] returns x^2+6*x+9

3. Factor

a) “factor(‘X^2-5*X+4’)” [ENTER] CAS [ENTER] returns (X-4)*(X-1)

b) “factor(x^2-5*x+4)” [ENTER] CAS [ENTER] returns (x-4)*(x-1)

4. Differentiation

“diff(‘COS(X)*SIN(X)’)” [ENTER] CAS [ENTER] returns -SIN(X)*SIN(X)+COS(X)*COS(X)

“simplify(‘-SIN(X)*SIN(X)+COS(X)*COS(X)’)” [ENTER] CAS [ENTER] returns 2*COS(X)^2-1

5. Summation

“sum(‘N^3’,’N’,1,9)” [ENTER] CAS [ENTER] returns 2025

6. Solving

“zeros(‘X^3-6’)” [ENTER] CAS [ENTER] returns [1.81712059283]
