Calc III Question ? *****


Let f(x,y,z) = x siny + y cosz . Find, a. f(0,0,0), b. f(1,p/2,p), c. f(1,p,p/2), d. [d/dx]f(x,x,x), e. [d/dx]f(x,2x,3x), f. [d/dy]f(y,y,0).

  • a = 0,b = 1-p/2,c = 1,e = sin2x+2cos3x
  • a = 0,b = 1-p/2,c = 0,f = 1+siny + ycosy
  • a = 0,b = 1-p/2,c = 0,d = (1-x)sinx + (1+x)cosx
  • a = 0,b = p/2,d = (1-x)sinx + (1+x)cosx
  • a = 0,c = 1,e = sin2x+2cos3x +x(2cos2x -6sin3x)
