I need to say what that figure is, but I'm not sure.... I don't want to get my billions and, maybe, trillions, mixed up.

Thanks.

The measurement of the edge of a cube is found to be 14 inches, with a possible error of 0.04 inch. Use differentials to approximate the maximum possible propagated error in computing the volume of the cube and its surface area?

Estimate the maximum allowable percent error in measuring the side if the error in computing the volume cannot exceed 2%. ds/s% = ?

here the question :
list the function below from lowest asymptotic order to highest asymptotic order.If any two (or more) are the same asymptotic order, indicate which.
a.start with these basic function:
n 2^n n lg n n^3
n^2 lg n n-n^3+7n^5 n^2+lg n

b. combine the following functions into your answer for part (a).assume 0 e^n root n 2^n-1 lg lg n

Hello. I have been trying to solve this problem for so long but it's just too hard. I don't understand it.

Does anyone know how to find the 1st derivative and 2nd derivative of √2x*sinx (the square root of 2x times sinx. using the 1st and 2nd derivative tests.

I know that I have to use the product rule with the chain rule but it is not working and my teacher said my answer is wrong.

Any answers are appreciated, I just want to understand how to do it.

Thank you!
