Equation of tangent plane to the sphere at the point (1, 2, 3) to the sphere 3(x2 + y2 + z2) - 2x - 3y - 4z - 22 = 0
1
x(1) + y(2) - 1/3(x + 1) - 1/2(y + 2) - 2/3(z + 3) + 22/3 = 0
2
x(1) + y(2) + z(3) - 1/3(x + 1) - 1/2(y + 2) - 4/3(z + 3) + 22/4 = 0
3
x(1) + y(2) + z(3) - 1/3(x + 1) - 1/2(y + 2) - 2/3(z + 3) + 22/3 = 0
4
x(1) + y(2) + z(3) - 1/2(y + 2) - 2/3(z + 3) + 22/3 = 0
