    Maths, Addmaths and Statistics: Post your doubts here!

    Anyone having problems in rotation, these are the shortcuts to determine the coordinates under specific rotations: For 90* clockwise : (x,y) -->(y,-x) For 90* anti-clockwise : (x,y) -->(-y,x) For 180* clockwise/anticlockwise : (x,y) -->(-x,-y)

    Oh well, that's easy :D If a triangle is shown on a graph and another traingle is shown on some other place in a different position and the vertices shown, like the first triangle has vertex A (3,1) and B (5,1) and they are mapped onto (-4,-2) and (-6,-2) respectively, then, use this method : (...

    The general equation is : a(x-h)^2 + k. Now if you expand this you will get: ax^2 - 2ahx + ah^2 + k Compare this with the equation given. a is the coefficient of x^2, so look for the co efficient of x^2 in the equation given, It is 2. so a =2 . Likewise, -2ah = -6 (coefficients of x). this will...

    Exactly, the range tells you the +ve positive and -ve height of the graph, like how high and low does it go in y-values. While the range, is to what extent the graph goes to the left/right. So for a restricted domain, like the one above, you will have restricted range, and vice versa. If not...

    year ? :D it will be o.5 se 13. because using the 'completing the sqaure' method you'd get the value of k to be 0.5 a(x-h)^2 +k
