d/dx (0) - d/dy (6xy+e^(-x^2)) ∫0 to 1 ∫0 to 1 (-6x) I've tried to find the limits of x by setting up x = x^2, which then gives me x = 0, and x = 1, and for y, I use √y=y, which gives me y = 0, and y = 1 Would those be the right limits for the double integral?

But there is no "dy" , I still don't understand that. Would the limit of x is from 0 to 1, and limit of y is from y to √y ?

Homework Statement Let C be the boundary of the domain enclosed between y = x^2 and y = x. Assuming C is oriented counterclockwise. Evaluate the integral ∫c (6xy+e^(-x^2))dx Homework Equations I was thinking of using Green's Theorem. Would be the approach be correct? The Attempt at a...

Please help !

A small steel wire of diameter 1.4 mm is connected to an oscillator and is under a tension of 6.3 N . The frequency of the oscillator is 63.0 Hz and it is observed that the amplitude of the wave on the steel wire is 0.50 cm. a)What is the power output of the oscillator, assuming that the wave...

Problem: The center of a 1.30 km diameter spherical pocket of oil is 1.30 km beneath the Earth's surface. Estimate by what percentage g directly above the pocket of oil would differ from the expected value of g for a uniform Earth? Assume the density of oil is 8.10x10^3 kg/m^3 Should I use...

Isn't it meters?

The position of an object is given by x=At+Bt^2, where x is in meters and t is in seconds. a)What are the units of A? (express answers in terms of m and s) b)What are the units of B? (express answers in terms of m and s) I know this may sound silly, but I really don't understand what the...

A child, who is 45 m from the bank of a river, is being carried helplessly downstream by the river's swift current of 1.0 m/s . As the child passes a lifeguard on the river's bank, the lifeguard starts swimming in a straight line until she reaches the child at a point downstream. a)If the...

I calculated that, and entered it in the system as 4.3 x 10^7, and it was right. This was for an online homework problem. Thank you so much for your help. Have a great day !

So I would need to convert 5m/s to mm, which will then give me 5000mm/s? Then in order to fill the number of pencils pass each second, I would take 5000 mm/4 mm, which will then give me 1250 pencils? As for the problem I posted, um is micrometer, right? So then I would need to convert 1.2...

On an audio compact disc (CD), digital bits of information are encoded sequentially along a spiral path. Each bit occupies about 0.28 um. A CD player's readout laser scans along the spiral's sequence of bits at a constant speed of about 1.2 m/s as the CD spins. Determine the number N of...

So to calculate the time that the train travels at the constant speed (26.39 m/s), 240 m = 26.39 m/s x t Which then I will get 9.1 s?

I have solved the distance for the acceleration with the formula I posted above, which gives me 317 m. For the deceleration, the initial velocity is 26.39 m/s, right? And the final velocity is 0 m/s? If that is correct, I would get 174 m , and 13.1995 s. So for question a, the total distance...

I remember one.. Is it d = Vt + (1/2)(a)(t^2) ?
