Find the gradient field of the function.f(x, y, z) = z sin (x + y + z)
A. ?f = -cos xi - cos yj + (sin z - z cos z)k B. ?f = z cos(x + y + z)i + z cos(x + y +z)j + (sin(x + y + z) + zcos(x + y + z))k C. ?f = -z cos(x + y + z)i - z cos(x + y +z)j + (sin(x + y + z) - zcos(x + y + z))k D. ?f = cos xi + cos yj + (sin z + z cos z)k

a. What are the scalar tangential and normal components of acceleration of the projectile? b. What are the scalar tangential and normal components of acceleration of the projectile when the projectile is at its maximum height?
Use Cramer's rule to solve the system. If D = 0, use another method to complete the solution. 3x - 2y + 2z - w = 2 4x + y + z + 6w = 8-3x + 2y - 2z + w = 5 5x + 3z - 2w = 1
