Assuming image is required, and of is required, and a is required, and line is required, the following results were found.

  • Image of a Line Under Transformation By a Matrix

    A matrix is a linear transformation, which means that it sends a line to a line. To find the image of the line on transformation by the matrix we represent the line by the vector and multiply the vector by the matrix: From this we see that (1) (2)...

  • The Image of a Line Under a Transformation Represented by a Matrix

    Any transformation represented by a matrix whose entries are numbers is linear. The matrix will send a line to a line. The transformed line will in general be rotated and scaled, but it will still be a line. For example, suppose a transformation is...

  • The Three Point Trick

    The Three Point Trick is a method of finding the equation of the image of a generalized circle – a circle or line (a line can be considered a circle of infinite radius) – after a generalized mobius transformation. Any circle is completely defined by...

  • MRI Scanners

    Magnetic resonance imaging (MRI) uses the body's natural magnetic properties to produce high resolution images of the inside of the body. It does this using the properties of the hydrogen ion. The hydrogen proton can be likened to the planet earth,...

  • Computerised Axial Tomography

    A X ray is a two dimensional image, so parts along the same line of sight from the X ray source is superimposed on each other. This can be overcome by taking X rays at different angles, This is the principle behind 'computerised axial tomography or...

  • X - Rays

    On 8 November 1895, Willhelm Röntgen, a physicist working at the University of Wurzburg discovered X rays when a photographic plate shut in a draw was found to be exposed when left close to a sample of uranium salt. Röntgen's work provided him with the...

  • Gravitational Lensing

    Gravitational lensing occurs when a large galaxy lies between the Earth and some distant object of interest. As this light moves away from the object in the rough direction of the earth, some of it might pass close to the intervening galaxy in such a...
