Alright, this week nothing happened really so I'm going to explain the Trapezoidal Rule because that's the only thing we learned this week besides the review we did for our upcoming test.
The trapezoidal rule is (bear with me I'm doing this on my phone):
T= (h/2)(y0+ 2y1+ 2y2+...2yn-1+ 2yn Yes, this looks scary. But I can explain what it really is. The h at the beginning is found by taking the numbers for a and b (x-axis values), subtracting a from b (aka b-a), and then dividing that number by n (number of subintervals). The y0, y1, etc values are the y values that are at the x values where the subintervals were places. This rule is all about plugging in really. It's a piece of cake when you practice it a few times and know what each thing means.
