EXP2HYP

 

 

 

 

Type:

Function

 

 

Description:

Converts expressions involving the exponential function into expressions with hyperbolic

 

functions.

 

 

Access:

Catalog, …µ

 

 

Input:

An expression

 

 

Output:

The rewritten expression.

 

 

Flags:

Exact mode must be set (flag –105 clear).

 

 

 

Numeric mode must not be set (flag –3 clear).

 

 

Example:

Rewrite in terms of hyperbolic functions the expression e5 ⋅ ln(x)

 

Command:

EXP2HYP(EXP(5*LN(X)))

 

 

Result:

SINH(5*LN(X))+COSH(5*LN(X))

 

 

EXP2POW

 

 

 

 

Type:

Function

 

 

Description:

Simplifies expressions involving the composition of the exponential and logarithmic functions.

 

Compare this to LNCOLLECT which combines logarithmic terms; the difference is shown in the

 

results of the second example used here and for LNCOLLECT.

 

Access:

!Ú REWRITE

 

 

Input:

An expression

 

 

Output:

Command

 

 

Type:

 

 

Description:

Expand Products Command: Rewrites an algebraic expression or equation by expanding products

 

and powers. This command is similar to the old HP 48G series command, with minor

 

modifications (such as adding RISCH for integration).
