Electronic bulletin board for DERIVE users
An independently operated, electronic bulletin board has been established
for the exchange of information concerning the DERIVE program. Soft
Warehouse will periodically check the board to answer technical questions.
The phone number in Illinois, U.S.A. is (217) 337-0926. The board supports
both 1200 and 2400 baud modems (no parity, 8 data bits, 1 stop bit).
Changes to DERIVE since printing of manual
1. Powers of any system or user-defined function can now be entered by
putting the power immediately after the function name. For example,
entering sin^2 x is equivalent to sin(x)^2 or (sin x)^2. As this
example shows, this can save having to type a pair of parentheses.
2. Use ADJOINT defined in the utility file VECTOR.MTH to compute the
adjoint of a square matrix.
3. POLY_COEFF(u,x,n) defined in MISC.MTH returns the coefficient of the
x^n term in the polynomial u(x). POLY_DEGREE(u,x) returns the degree of
the polynomial u(x). (Contributed by Gert H. Renkema of Netherlands)
