Find the linearization $L(x, y)$ of $f(x, y)=x^{2} y^{3}$ at $(a, b)=$ $(2,1)$ . Use it to estimate $f(2.01,1.02)$ and $f(1.97,1.01)$ and compare with values obtained using a calculator.

Differentiability and Tangent Planes
a) Find the linearization of the function f(x, y) = x^3 ∑∑ y^2 + 9y at the point (2, 3). (if you forgot the formula, you can check your notes this time) b) Use the linearization you found to approximate (1.98)^3 ∑∑ (3.01)^2 + 9(3.01) c) Find the equation of the tangent plane to the graph of f at the point (2, 3, 48). (this should be very little work after doing part a))

4. Find the linearization of f(x,y) and use it to estimate the function value. Use L(x,y) = z0 + dz = z0 + ∇f · dr = z0 + fxdx + fydy. (1) (a) Write the linearization L(x,y) of the function z = f(x,y) = x^2 + 2y^2 + 1 at the point (1, 1) and (b) use it to estimate the value f(1.05, 0.95) [Answer. (a) L(x,y) = 4 + 2dx + 4dy. (b) L(1.05,0.95) = 3.9] (2) (a) Find the linearization of the function f(x,y) = x^3y^4 at the point (1, 1) and (b) use it to estimate the value f(0.96, 1.03) [Answer. ∇f · dr = 0 and L(0.96,1.03) = 1]
