Calculus

Approximate the area under the curve of f(x)=9-x^2 between x=-2 and x=3 by calculating the area of 5 rectangles for both left hand endpoints and right hand endpoints.

I have the left hand and right hand endpoints, what I need help in is solving for the actual area.

Thanks

  1. Remember that the area is the sum of little rectangles, with width 1 and height f(x) at the endpoints.

    There are lots of good online Riemann sum calculators, such as this one:

    Just plug in your data and see the calculations to verify your results.

    Well, first graph the graph of f(x)=-1/10x^2 + 3 2. We are going to approximate the area between f and the x-axis from x = 0 to x = 4 using rectangles (the method of Riemann sums). This is not the entire area in the first

    Find the area cut off by x+y=3 from xy=2. I have proceeded as under: y=x/2. Substituting this value we get x+x/2=3 Or x+x/2-3=0 Or x^2-3x+2=0 Or (x-1)(x-2)=0, hence x=1 and x=2 are the points of intersection of the curve xy=2 and

    how do you find the horizontal and vertical assymptotes of the curve y= x/ x+3 and also the intercepts. so that you can approximate the area under the curve from x=1 to x=5 using 5 function values? THANKYOU,

    Use the mid-point rule with n = 4 to approximate the area of the region bounded by y = x^3 and y = x. I just need to know how to use the midpoint rule when the area is between two curves instead of under a curve. Help please.
