 A trig identity 2013-01-04 Tehmas pose la question :Prove sinC+sinD=2sin(C+D/2)cos(C-D/2)Harley Weston lui répond. 2 + f(x) and f(x) + 2 2011-11-21 Beth pose la question :Do you do y=2+f(x) the same way as if the 2 came after the equation such as y=f(x) +2 when graphing?Penny Nom lui répond. Reflection in the line y = x 2010-07-21 tousif pose la question :Find the 2 x 2 matrix which represents a reflection in the line y = x? Please help....Penny Nom lui répond. The graph of f(x)=1/x -2 2009-11-29 Kapilan pose la question :Please answer the following question: Sketch the graph of f(x)=1/x -2Harley Weston lui répond. Transformations 2009-02-04 Vickie pose la question :Hello, My daughter had a question on her Week By Week about transformations and I can't remember what transformations will result in proportional figures. If a transformation looks like it is smaller what is that called? Also if the figure looks bigger what is that called? VickieRobert Dawson lui répond. Transformations and compositions 2007-11-29 mary pose la question :Is there any possible relationship between composite functions and the concept of function transformations?Harley Weston lui répond. A rotated rectangle 2007-04-16 Graham pose la question :There is a circle inside which from the centre to the top is a rectangle. Size is unimportant. If I the rectangle is at 0 degrees and I know the co-ordinates of the 4 corners I can do a check to see whether a given point x,y is inside the rectangle or not. Question : If the rectangle is rotated by 50 degrees how do I check then as the lines of the rectangle are not perfectly straight with regards to x and y ie at 0 degrees x changes but y is constant and vice versa. At 50 degrees x and y change together.Penny Nom lui répond. Prove that a rhombus' diagonals are perpendicular 2005-10-02 Tania pose la question :How do you prove that a rhombus' diagonals are perpendicular using the 2 column proof method?Walter Whiteley lui répond. A torus and a sphere 2005-03-27 Tony pose la question :Is it possible to shrink a torus into a sphere? Andrei Volodin and Penny Nom lui répond. A sequence of transformations 2005-01-03 Abraham pose la question :Please go to this web site and look at number 31. http://www.nysedregents.org/testing/mathre/matharch/mathbtestau02.pdf That is the New York state education web site. Can you tell me if my answer would be marked correct? My answer was Transformation of 4,-3 (T 4,-3) followed by a reflection in the x-axis.If I graphed the question and wrote that, would I get full creditHarley Weston lui répond. Transformations of pattern blocks 2003-02-06 Cheryl pose la question :I am trying to help my 8th grade son with Transformations - use of patttern blocks. He has to trace a figure and reflect it across the x-axis, which I can do, but then it indicates include ordered pairs - that confuses me.Penny Nom lui répond. Polar coordinates 2000-02-24 Tran Trung pose la question :How do I convert r = 2/(2sin(theta) - 3cos(theta)) to rectangular and x2 + y2 -2y = 0 to polar form?Harley Weston lui répond. Shape-preserving transformations 1999-05-04 J McAndrew pose la question :A shape preserves its shape if a rotation, translation or scaling is performed on it. Are these the only continuous transformations which have this property? These transformations if performed on the parts and then summed have the same effect as the transformation being applied to the whole; are these linear transformations? Who, and what area of mathematics has classified all transformations of this type completely?Chris Fisher lui répond.
