(1 point) A function f is defined on the whole of the x, y-plane as follows: f(x,y)0 fy0 otherwise For each of the following functions g determine if the corresponding functionf is continuous on the whole plane. Use "T" for true,"F" for false 2. g(x, y) 9x2y 3. gx, y)-4 sin) 4. g(x, y) xy sin(xy) 5. g(x, y) 3xy (1 point) A function f is defined on the whole of the x, y-plane as follows: f(x,y)0 fy0 otherwise For...
(1 point) If F is a function defined by F(y) = 3y2 - 1. a. Find F(0) -1 b. Solve F(y) = 0. The answer should be in the form y-23, and not simply give the numerical value of the solution, like 23. If there are two solutions, use the word or, as in y-23 or y=12. If you need to use the square root sign, as in 23, type it like sqrt(23) y=0
Hello can you help me? How can I solve this question? x By .(x, y) = (0,0) f (x, y) = xraya (x,y) = (0,0) no+? for this function at (0,0) point, is this faction continuous or Show it properly
Thanks for answering in advance. a, b Let f(x) be the |b al- 2. Let f(x be a continuous function defined on periodic extension of f. Find the Fourier coefficients of f in terms of integrals of f a, b Let f(x) be the |b al- 2. Let f(x be a continuous function defined on periodic extension of f. Find the Fourier coefficients of f in terms of integrals of f

solve for L, A0, An, Bn, and f(x). (1 point) y= f(x) is the function illustrated below, defined only on в€ (0,6): Б 10 -1. -1 Compute the Fourier coefficients for f(x). Since we are only interested in the interval 0,6|, we don't care what happens anywhere else. We can pretend the function is zero on -6,0 and periodic: 10 57 19 (1 point) y= f(x) is the function illustrated below, defined only on в€ (0,6): Б 10 -1. -1...
Please solve for part (b) and (c) thank you! 1. Consider the function f(x) = e-x defined on the interval 0 < x < 1. (a) Give an odd and an even extension of this function onto the interval -1 < x < 1. Your answer can be in the form of an expression, or as a clearly labelled graph. [2 marks] (b) Obtain the Fourier sine and cosine representation for the functions found above. Hint: use integration by parts....
2. Consider the function f : R2 → R defined below. r3уг_ if (x,y) (0,0) f(x,y) = if (x, y) (0, 0) (a) Prove that f is continuous at (0,0) (b) Calculate the partial derivatives (0,0) and (0,0) directly from the definition of partial derivatives. (c) Prove that f is not differentiable at (0,0).
(1 point) Below is the graph of the derivative f'(x) of a function defined on the Interval (0,8). You can click on the graph to see a larger version in a separate window. n (A) For what values of x in (0,8) is f(x) increasing? Answer: Note: use interval notation to report your answer. Click on the link for details, but you can enter a single interval, a union of intervals, and if the function is never increasing, you can...
Give an example of a function f(x, y) that is defined on R2 and has only hyperbolas as its level sets. At the moment I have x2 - y2 = k (where k is a constant) as my answer. But I'm not sure if that is correct. It seems to work except when k = 0, which I'll have only two lines (y = x and y = -x) so I'm not too sure what should I do with it....
