Question

Basic integration problem

Answer 1

You're basically adding up the areas of 6 rectangles where the bases are all 1 and the heights are the v value for the midpoint of each rectangle

Answer 2

yeah i got that, but then what do we choose for the v value?
i guessed and approximated v values at each midpoint and then got the final answer as 77.5. it was wrong. ><

Answer 3

That's really low considering the 1st rectangle is above 50 and the 2nd is about 40. I eyeballed 58, 40, 28, 18, 10, and 4. So the area would be 158. Even that probably wont be right because the spacing they gave is so awful

Answer 4

Oh.. hahahah i did a stupid mistake. You're right, I somehow halved my answer for some reason. So yeah, I got 155. Thanks! ^^
