This week we learned about derivatives and the first thing we did to help us understand was create graphs on gifsmos. It represented how the slope of a line got more accurate the closer the two points got together which turned it from a secant line into a tangent line. The activity at the beginning of the hour helped me to understand that concept. I struggled a little bit at first because I just didn't know where to start. Talking with my classmates definitely helped me get on the right track. I was almost finished with my first graph but was stumped on how to get the sliders to move so I asked Mr. Cresswell who helped explain things. The first graph required a stationary point with one slider number f(a) and the second graph both sliders numbers moved by adding f(b) and slope formula m=(f(a)-f(b))/(a-b), the avg rate of change. For the third graph I kept everything the same expect for the original f(x)=.5x^2 function. I changed it to f(x)=sinx^2 and it still worked because of the f(a) an f(b) slider points.
