Input:
An expression with complex linear and exponential
terms.
Output:
The expression with logarithmic and exponential sub
expressions converted to trigonometric and inverse
trigonometric expressions.
Flags:

Nmneric mode must not be set (flag -03 clear).
Must be in complex mode (flag -103 set).
Example: Express e'"'^ in trigonometric terms.
Command:
SINCOS(EXP(i*X))
Result:
COS(X)+iSIN(X)
SOLVE
Type: Command
Description:
Finds zeros of an expression equated to 0, or solves an
equation.
Access:
Symbolic solve, Rgay)
Input:
Level 2/Argument 1; The expression or equation.
Level 1/Argument 2: The variable to solve for.
Output: A list of zeros or solutions.
Flags:
If exact mode is set (flag -105 clear) and there are no
exact solutions, the command returns a null list even
when there are approximate solutions.
Example: Find the zeros of the following expression:
- X - 9
Command:
SOLVE(X"3-X-9,X)
Result:
{X=2.24004098747}
