Explanation Given: The mapping G ( u , v ) = ( e u , e u + v ) Calculation: For one -one Suppose that G ( u 1 , v 1 ) = G ( u 2 , v 2 ) . We need to show that ( u 1 , v 1 ) = ( u 2 , v 2 ) ( e u 1 , e u 1 + v 1 ) = ( e u 2 , e u 2 + v 2 ) We get e u 1 = e u 2 which gives u 1 = u 2 and ( e u 1 + v 1 ) = ( e u 2 + v 2 ) gives u 1 + v 1 = u 2 + v 2 and hence v 1 = v 2 Thus G is one to one. The image of the exponent function is ( 0 , ∞ ) and x = e u , y = e u + v Here we can take any values for u and v We get x = e u > 0 , y = e u + v > 0 which means the image of G is first quadrant of the x y -plane and the axes are not included...

Family of Curves

A family of curves is a group of curves that are each described by a parametrization in which one or more variables are parameters. In general, the parameters have more complexity on the assembly of the curve than an ordinary linear transformation. These…

XZ Plane

In order to understand XZ plane, it's helpful to understand two-dimensional and three-dimensional spaces. To plot a point on a plane, two numbers are needed, and these two numbers in the plane can be represented as an ordered pair (a,b) where a and b are…
