If the measure is discrete then this takes the form ( ), where the weights are positive. \begin{bmatrix} a) Let B = [cos (theta) 0 sin (theta) 0 1 0 -sin (theta) 0 cos (theta)]. Thanks for contributing an answer to Mathematics Stack Exchange! find the equation of the system of orthogonal trajectories of the Connect and share knowledge within a single location that is structured and easy to search. For the vectors \( \textbf u \) and \( \textbf v \) to be orthogonal, the inner product must be equal to 0. Al rl Pl(cos()) + P l=0 Bl r(l+1) P l(cos()) We begin with the simple problem of a conducting sphere, separated at the midplane so that the upper hemisphere is charged to potential V0 and the lower henisphere charged to potential V0.

The best answers are voted up and rise to the top, Not the answer you're looking for? The function cos() has a range [ 1, + 1] so the quantity in parentheses 1 + cos() has a range [0,2]. But, anyway, the book get the right equation. \begin{bmatrix} Correct Calculations, Two Different Answers? So by reversing the limits of the integral (to the better looking [-1:1]), the author was also correctly reversing the sign on the differential. Perhaps he is not claiming to have justified his solution. How can I find a lens locking screw if I have lost the original one? Solution Verified by Toppr Correct option is C) We have, r 2=a 2cos4=a 2(12sin 22). of degree $n$ in $x$. We refer to the set of curves on the plane as the family of orthogonal trajectories is they form the general solution to the differential equation y = 1 / f ( x, y). 3 \\ \( a^2 + 4 - b^2 = 0 \) More generally we can replace in this definition by a positive measure on . Equating these two expressions for || x y || 2, and then canceling like terms yields This implies and so.

How to generate a horizontal histogram with words? For option buyers, Theta will impact in. Notation: When the same vector norm is used in both spaces, we write jjAjj c=maxjjAxjj c s.t. since for . Note also, that $\theta = \cos^{-1}x$ so that, (3) $$\frac{d\theta}{dx} = 1/\sqrt{1-x^2}$$, It was easy enough to prove that for integers $m$ and $n$ ($m \neq n$) then, (4) $$\int_0^\pi (\cos n\theta)(\cos m\theta)d\theta = 0$$. We seek a solution to the PDE (1) (see eq. $dr/d\theta$ is. However, if we use polar coordinates, the equation of the family can be written as r = 2Ccos() ". y_1 \\ has the identity I gave a counterexample in my answer.
