3. Consider the vector field F(x, y) + 2y F dr, where C is the circle (r-2)2 +y2 = 1, oriented counterclock (a) Compute wise (Hint: use the FT of line integrals. We could not use it for the circle centered at the origin, but we can use the theorem for this circle. Why?) (b) Let 0 be the angle in polar coordinates for a point (x, y). Check that 0 is a potential function for F 3. Consider the...
The shortest distance across the water from an island dock (point D) to a straight shoreline is 9 miles. Let the closest point on the shoreline be A. An amphibious vehicle makes a trip from a depot at a point B on the shoreline that is 20 miles away from A. Suppose that it travels 20 – x miles toward A along the shoreline (where 0 ≤ x ≤ 20) to a point C, then strikes out across the water...
Determine the Resultant, R, and Equilibrant, E, vector from the components of A and B A: 2.45 N at 60 degrees from the positive x-axis B: 1.47 N at 0 degrees from the positive x-axis a.

The matrix Xi contains n observations on ki explanatory variables which are believed to affect individual wealth in Australia, and he matrix X2 contains n observations on k2 explanatory variables which are believed...
Problem: Given a rotation R of R3 about an arbitrary axis through a given angle find the matrix which represents R with respect to standard coordinates. Here are the details: The axis of rotation is the line L, spanned and oriented by the vector v (1,一1,-1) . Now rotate R3 about L through the angle t = 4 π according to the Right 3 Hand Rule Solution strategy: If we choose a right handed ordered ONB B- (a, b,r) for...
Please help write a code in C that asks to translate from an infix expression (e.g. a * (b + c ) ) to a prefix notation (i.e., *a+bc) . You may assume that all the variables are one char and that the operators are limited to +, - , *. The infix expression is entered by the user from the command prompt. It has a maximum length of 20 characters and it must be correct – you do not...
