need serious help :) (values of a and b that make f continuos everywhere

f(x) = { A+x, if x ≤ -π
{ A sin(x) -1, if -π<x<π
{ B+ cos(3x), if x≥π

π=pi (symbol is showing up wierdly for me

kinda left this late as i needa have this problem solved in 2 hours, sorry about this and any help would be appreciated

Choose A such that A + x = A sin(x) - 1 when x = -n.

Same approach for B.

To be continuous, the piecewise function must have the same values when evaluated at the breakpoints in the domain from both the left and the right.

You should be able to get a system of equations to determine the coefficients A and B.
