[Question 1]:
(i) State the equation for the tangent plane to the graph of z = f (x,y)
(ii) Thus find the equation of the tangent plane to the surface z = x2 + y2 + 3 at the point (2,3,16)
(iii) Let f (x,y)= log(x-3y)and find the equations of the tangent at (7,2,0) and use this equation to estimate: f (6.9, 2.1).
Step by step explanation needed thank you in advance =)
