Okay let me rephrase my question with the aid of proper symbols :)
\int_{-2}^2 \int_{x^2}^4 \! (6x^2+2y) \text{ dy dx} =
2*{\int_{0}^4 \int_{0}^{y^{1/2}} \! (6x^2+2y) \text{ dx dy}}
Is this just coincidence or is this always true when you have a Region formed by two even functions as in...
Homework Statement
R is the region bounded by y=x^2 and y=4. evaluate the double integral of f(x,y)=6x^2+2y over R
After drawing the region I was wondering if I could just work with the first quadrant and then double my solution, because both y=x^2 and y=4 are even functions so my question is...
i was told i could calculate a torque force by my teacher :P
Its modeled on a single propeller plane, so there is no cancelation of forces.
This is a real scenario, and I'm just trying to experiment with it :)
Hi all, first time posting so let's see how it goes!
My problems are with a piece of physics coursework I'm doing for my A-level courses. I chose to investigate the 'torque effect' on single propeller planes. (If you are unsure of what this is, its basically Newtons third law, reasoning that...
