EXP2HYP

CAS: Convert expressions with the exponential function into expressions with hyperbolic functions.

EXP2POW

CAS: Simplify expressions involving the composition of the exponential and logarithmic functions.

EXPAN

Type: Command
Description: Expand Products Command: Rewrites an algebraic expression or equation by expanding
products and powers. This command is equivalent to the old HP 48G series command, with
minor modifications (such as adding RISCH for integration).

EXPAND

CAS: Expand and simplify an algebraic expression. More in-depth than EXPAN and often provides
better simplification.

EXPANDMOD

CAS: Expand and simplify algebraic expressions, modulo the current modulus.

EXPFIT

Type: Command
Description: Exponential Curve Fit Command: Stores EXPFIT as the fifth parameter in the reserved variable
PAR, indicating that subsequent executions of LR are to use the exponential curve fitting
model.
LINFIT is the default specification in PAR.

EXPLN

CAS: Transform the trigonometric terms in an expression to exponential and logarithmic terms.

EXPM

Type: Analytic Function
Description: Exponential Minus 1 Analytic Function: Returns e
