Let f : [a, b] → R be a differentiable function and let P be a partition of [a, b]. Show that L(P, f′) ≤ f(b) − f(a).   Hint: Use the Mean-Value Theorem. (Recall that, if P... Double integral - calculating area

Calculate the area of the region bounded by the two curves, y = 4 - x2 and y = x + 2.   The answer is meant to be 9/2 but I just cannot get it!!! Maybe my bounds are incorrect......

a) 87.75 b) 15.75 c) 11.25 d) 6.75 Slicing cube packed with spheres to get slices with same volume

Lets say, I  have a cube with with Volume = a*a*a. I also have a sphere (hole) with coordinates X,Y,Z and radius r in the cube. My task is to slice the cube (perpendicularly to Y), when each... How do I solve this Integral? (Pic attached in link)

I have been stuck on this integral for 3 hours. Here is what I have so far.. : https://ibb.co/mWAC7x ∫dx/(x+1) - ∫dx/(x+2) = log| (x+1)c/(x+2) | This was on my first Calc 2 quiz: $2\int_{-3}^{3}e^x^4dx$

I feel that there should be another x in the problem so that u sub works, or something, as it is I believe it is a partial gamma function or something, but I know we should not learn those until much... I have a question regarding integrals, which I have not been able to solve

The function to be integrated is the following: f(x)=(√x)/(x2 + ln(1+x))   In addition to this we were asked to confirm if the function converges or not. When plotted it is...

Calculate the integral below, assuming that ∫50f(x)dx=5∫05f(x)dx=5 and ∫50g(x)dx=12∫05g(x)dx=12. ∫50(6f(x)−13g(x))dx= What M value should I use? (how do i find it)

I was asked to calculate the area between two functions, y=e^x and y=x using midpoint riemann sums from 0-2 with n=4. so i found my answer by subtracting the second sum from the first. The second... Sigma notation with area under a curve, lower and upper rectangles

I got the answer to this problem from my teacher but I don't understand why that's the answer: y=√1+x^3 , domain 1≤x≤2 and with 50 intervals therefore width is 1/50.  The Sigma notation... What is the integral of a function: (e^(-x))cos(x/2) dx ??

The answer which I got was  (e^(-x))sin(x/2)-cos(x/2)(e^(-x))     However all the math solvers on the internet are giving different answers. Could you clear things up and tell... Net change/word problem/integrals

Water flows into a reservoir at a rate of 1500 + 7t2 gallons per hour. since there is a tiny hole in the reservoir, the water leaks out at a rate of 4t + t2 gallons per hour. What is the net...
