Two kinds of delta

Preben Alsholm — Fri, 02 Nov 2012 19:15:11 Z

You have two different delta's it appears. You are assigning to one delta[min] and using another in the definition of A in the cosine. The output prints the latter delta the same as the former though.

Solution: Enter the two delta's in the same way (or much to be preferred in my opinion: don't use the default 2D input but use 1D input).

Epsilon

No problem with epsilon.
Perhaps you can better use "Maple notation" for input display.

Thanks for the tips. Why does the input

Thanks for the tips.

Why does the input mode always jump from "C Maple Input" to "C 2D Input", when I for example paste in the above lines from the browser?

Thanks. Must have mistyped the subscript

Thanks. Must have mistyped the subscript of delta min in the second place.

After retyping it, the picture changes. I also wonder why epsilon is not written as greek ε in the

equation.

evalf

Try evalf(A);

It is easier for us to be helpful if instead of a picture you upload a worksheet via the fat green arrow in MaplePrimes.

evalf(A); that's it

@Preben Alsholm :

Thanks. That's it. Still wondering why the epsilon is not printed. Might it be a reserved greek character

in other contexts?

And thanks for pointing me to the "green arrow". That's much easier :)
