![]() Step 2: Identify the location of endpoints or. Step 1: Identify the type of congruence transformation: reflection, rotation, translation. Going to be preserved are going to be your angles. Steps to Graph a Sequence of Congruence Transformations. These three transformations, the only thing that's Segment lengths got lost through the dilation but we will preserve, continue to preserve the angles. It would preserve both, but once again our Reflection which is still a rigid transformation and But angles are going toĬontinue to be preserved. So this is a rigid transformation, it would preserve both but we've already lost our segment lengths. Then we have a rotationĪbout another point Q. So already we've lost our segment lengths but we still got our angles. So the first transformation is a dilation. ![]() ![]() Lengths, both or neither are going to be preserved. And so pause this video againĪnd see if you can figure out whether measures, segment ![]() So both angle measure, angle measure and segment length are Then you have a translation which is also a rigid transformation and so that would preserve both again. It would preserve both segment lengths and angle measures. Of them be preserved? Alright so first we have a So pause this video and thinkĪbout whether angle measures, segment lengths, or will either both or neither or only one You're gonna preserve both angles and segment lengths. So in general, if you'reĭoing rigid transformation after rigid transformation, We're talking about a stretch in general, this is going To be different than AC in terms of segment length. And my segment lengths are for sure going to be different now. Well what just happened to my triangle? Well the measure of angle C is for sure going to be different now. Out so that we now have A is over here or A prime That we take these sides and we stretch them And if you were to do a vertical stretch, what's going to happen? Well let's just imagine Then they say a vertical stretch about PQ. Well a reflection is alsoĪ rigid transformation and so we will continue to preserve angle measure and segment lengths. Measures and segment lengths are still going to be the same. Preserve segment lengths? Well a translation isĪ rigid transformation and so that will preserve both angle measures and segment lengths. The Various Kinds of Algorithmic Sequence Transformations. What is this going to do? Is this going to preserve angle measures and is this going to Part of the book series: Springer Series in Computational Mathematics (SSCM, volume 11). Then we do a reflection over a horizontal line, PQ, then we do vertical stretch about PQ. What we're now gonna thinkĪbout is what is preserved with a sequence of transformations? And in particular, we're gonna Example: Applying a Learning Model Equation A horizontal reflection: f(t)2t f ( t ) 2 t A vertical reflection: f(t)2t f ( t ). neither with the results of quadratic equation nor with the intervals of monotony(sign) of the derivative.Videos, we've thought about whether segment lengths or angle measures are preserved with a transformation. And it is decreasing on ( − ∞, − 1 − 45 2 ), then increasing on ( − 1 − 45 2, − 3 ) then decreasing on (-3,2) then increasing again on ( 2, ∞ ). But Instead the solutions of the third equation are x 1 = − 1 − 5 2 and x 2 = − 1 + 5 2. Therefore our function should increase on the interval ( − ∞, − 1 − 45 2 ) then decrease on the interval ( − 1 − 45 2, − 1 + 45 2 ) then increase again on the interval ( − 1 + 45 2, − 1 − i 3 2 ) and decrease again on ( − 1 + i 3 2, ∞ ). If you'll do the sign of the first one it'll be x 2 + x − 11 0 therefore x 1 = − 1 + 45 2 and x 1 = − 1 − 45 2, the last one x 2 + x + 1 > 0 has the solutions x 1 = − 1 − i 3 2 and x 2 = − 1 + i 3 2 (here I think that I did a mistake). The derivative is defined in the following order:ĭ d x f ( x ) = − x 2 − x + 11 ( x + 3 ) 2 e 2 − x for x 2. Some of them always use the same formula involving a. Some doubts with the sign of a derivative INTRODUCTION In numerical analysis the sequence transformations used are not all of the same kind.
