Please show picture over a rectangle.

a) Let f(x,y) = 2sin(πx)−3cos(πy). Calculate Uf(P) and Lf(P) over the partition P = {1,1.5,2}×{2,2.5,3}.

b) Explain what techniques would be necessary to calculate Uf(P) and Lf(P) for f(x,y) = 2sin(x)−3cos(y) over the partition P = {1,1.5,3}×{2,2.5,3}.

The value of f depends on two independent variables x and y as defined below: f(x,y)=x2+y2−x+3cos(x)sin(y) Function f has a minimum in the neighborhood of the origin (i.e. [0 0]). Find x and y which minimize f. Note: You are not allowed to use MATLAB built-in functions for optimization. Follow the logic of the derivative test: The minimum of f occurs where: ∂f∂x=0∂f∂y=0
