solve non-homogeneous de y" + y = sec^2x by finding-
the solution yh(x) to the equivalent homogeneous de
the particular solution yp(x) using variation of
parametrs
the general solution y(x) = yh(x) + yp(x) of the de
please explain the steps
f(x,y)=sin(2x)sin(y)
intervals for x and y:
-π/2 ≤ x ≤ π/2 and -π ≤ y ≤ π
find extrema and saddle points
In the solution, I mainly interested how to
findcritical points in case of the system of trigonometric
equations (fx=0 and fy=0).
