Review Log: Feb 10 - RI

RI:Is "The equation of each of these functions gives information about the transformation that can be applied to the graph of y = sin x to get their graphs." better? Better enough to redo it? I was a little unsure what "the function" at the end of your sentence referred to. RI- these words clear up any confusion in Scene 7 RI- is vertical transformations a standard enough description? transformations in the vertical direction? RI- I might have mimicked the instructions from Scene 11. RI- vertical reflection is a new term to me. Reflection in a horizontal line isn't, but I know what you are trying to do. RI- I found the directness of the statement "the graph of y=asinx **is** a vertical stretch **and** reflection of the graph of y=sinx." raised questions in my mind - both about the **is** and the **and**. RI Alternative? "...the graph of y = asinx is the image of the graph of y=sinx under both a vertical stretch and a reflection." or even "under a composition of a vertical stretch with/and a reflection". RI- like Scene 14 RI- is horizonal translation **to the right** better? Should we use this opportunity to ask about d=360 //degrees//? Scene 19 RI- I don't like the double negative at the top, I would prefer brackets around d.;I really like what the Show button does. RI- up until now the green reference graph was y=sinx - I think the user's attention should be drawn to the fact that this not the standard sine function. The green graph should perhaps be red and the other graph a new colour altogether. Some words to point out this fact would help too. RI- nice point. RI- I expected to see "phase shift" in the blue box of key properties and have it mentioned in the analysis of y= sin(x-d). RI I would characterize all of the above questions and suggestions as being unnecessary to address prior to the conference (except maybe Scene 19 and Scene 20 - since they don't involve re-recording). The rest we can tease out after the conference.
