1. The problem statement, all variables and given/known data Okay first one looks like this: Solve 1 ∫ (x2+x)dx 0 2nd: A bunny set the world record in 1997 at jumping the highest of all the other bunnies. The bunny's jump under the competition looks like: h(x)=4x-4x2. Where "h" is the height in meters and x is the distance from where the bunny started jumping. Use the derivitive to calculate the bunny's highest jump. 3rd: Determine the coordinates of the extreme points of the curve y=x3-3x+5 3. The attempt at a solution 1st: Never worked with this before in my life and I understand nothing about this, my textbook gives me an example like this : 4------------4 ∫x3dx = [x4/4] = 64-4 = 60. 2------------2 This example should be relevant to my problem as it's fairly similar but I don't understand how they got to x4/4 in the example. 2nd: I tried solving using the derivitive like this: h(x)=4x-4x2. h'(x)=4-8x and then putting -8x on the other side so 8x=4 x=2 but that fails since the answer is supposed to be 1m. 3rd: y=x3-3x+5 y'=3x2-3=0 x2 -1=0 Now what? am I on the right track?
