Chapter 1 Sturm’s Theorem 1.1 Sturm’s Thorem Definition 1.1 We define that the number of changed sign V (a1, · · · , an) for a = 1, · · · , an ∈ R is as follows. For the sequense (a1, · · ·...
A rectangle OABC rotates counter clockwise about the point O as shown in the diagram below, which is not drawn to scale Initially O is at (0,0), A is at (4,0), B is at (4,3), C is at (0,4). The diagram shows the rectangle after it has rotated through 20 ...
This experiment’s purpose is to determine the force of gravity using a simple pendulum. A simple pendulum consists of a heavy weight called the bob, supported from a fixed point about which the bob is free to swing by a string of insignificant mass. To calcul...

Introduction. A linear transformation, T, of the plane which maps the point P (x, y) onto the point P’ (x’, y’) is defined by the equations... First, it’s easy to think about so make it the coordinate of OABC as same as Part 1’s b). Which is O = (0, ...
