hi all, my proposal for a function to calculate directional derivative ( \( \bigtriangledown f \cdot \overrightarrow{v} \) ). It's a CAS program. Use: derivdir(f,v), where f is a function and v a vector. I would like to thank Han for his hints in making this program. Enjoy! Salvo Code:

Nice program. It works. Curious that DOT product should be written in lowercase letters. Also "local" seems to be necessary in lowercase. Thanks |
