I know that one can act a function on every member of a list using the map function, e.g.,
f(x):=block([x:x], x^2)$
foo:[1,2,3];
map('f,foo);
However, I haven't been able to work out how one would do the equivalent with an array of lists, and a…

How can I structure this equation?
I have tried doing this:
x:[0,4%pi];
solve(sin(x)=0.3,x);
and then solving for the equation but that didn't work because:
%pi is not an infix operator
Any suggestions and also how to solve the following in…
