Solved 1 Let F R2 R Be Given By F X Y Exy Sin F(x) ∈ y. following is some commonly used terminologies: 1. x is called the domain of f. 2. y is called the codomain of f. 3. if f(x) = y, then we say y is the image of x. the preimage of y is preimage(y) = {x ∈ x : f(x) = y}. 4. the range of f is the set of images of elements in x. in this section we deal with functions from a vector sapce. Prove that: a) f is an immersion and f (r 2) is homeomorphic to a torus, b) the frame e 1 = ∂ x ∂ f , e 2 = ∂ y ∂ f in f (r 2) ⊂ r 4 is orthonormal in the metric of f (r 2) induced by r 4. compute ω 1 , ω 2 , ω 12 , c) the gaussian curvature of the induced metric is identically zero. We can now summarize the expressions for the gradient, divergence, curl and laplacian in cartesian, cylindrical and spherical coordinates in the following tables: cartesian. (x, y, z): scalar function f; vector field f = f1i f2j f3k. gradient : ∇ f = ∂ f ∂ xi ∂ f ∂ yj ∂ f ∂ zk. 10 4 3 3 let f: r2 r be given by f(x,y) y. (a) find the gradient of f at the point (3,2), that is vf(3,2) (b) compute the directional derivative of f at (3, 2) in the direction of the vector (1,2). c) in which direction, at the point (3,2), is the directional derivative of f maximal and what is the directional derivative in that direction?.

Kelvin only needed to look at the solution near earth’s surface (figure 4.26) and, after a long time, determine what time best yielded the estimated temperature gradient known during his era (1 ° f (1 ° f increase per 50 ft). 50 ft). he simply chose a range of times with a gradient close to this value.
