Maxima: Round like in Excel
Is there a function which rounds numbers (even decimal numbers) like round() in Excel?
Example
Round 1,45 to one decimal: 1,5
Round 2,45 to one decimal: 2,5
There is a similar question but they use a different algorithm.

Symbolically solving equation for a given variable in Maxima
I can solve an equation using Maxima by using the commands below.
kill(all);
A:A; phase:phase; solve(A*cos(2*pi*f*t+phase)=y,phase);
And it gives me the correct answer.
phase=acos(y/A)-2*f*pi*t
But when I try and solve for just the top portion of…

Why is wxMaxima not integrating the following input, and merely polishing the input as a result instead?
When I input:
integrate((sqrt(x+sqrt(x+1))),x);
It results in:
integrate(sqrt(sqrt(x+1)+x),x)
The result is displayed in a more organized manner. However, it does not give me the integral. Why?

Series simplification in Maxima
I try
sum(k, k, 1, n+1)-sum(k, k, 1, n),simpsum;
Why does it give n+1?
collect(sum(k, k, 1, n+1)-sum(k, k, 1, n));
neither?
