a particle is moving with velocity v=k(yi^ +xj^). where k is constant and i^ and j^ are the components of vector. the general equation for its path is ?

dy/dt=kx

dy/dx=x/y

solving the differential equation

y^2-x^2=C

Before you start a new project, you need to set up the development environment folder structure so that files with a
similar purpose are in the same folder and are easy to find. For example, all JavaScript library files should be in the
scripts folder, all images should be in the images folder, and all CSS files and image files used in the CSS should be
in the styles folder. To set up your development environment, create a new folder (called for example, jQueryLearn)
where you want to keep all your HTML (.htm and .html) files and folders that contain JavaScript (.js) files, CSS (.css)
files, and image (.jpg, .png, .bmp, and so on) files.
