1. y(x^2+xy-2y^2)dx+x(3y^2-xy-x^2)dy=0
2. (x+ysin y/x)dx-xsin y/x dy=0

v((2v^2) u -3) du + (3u^2) (v^2) - 3u + 4v) dv = 0

y' = (x + xy^2)/4y

ydx = {(e^ (3x) + 1)} dy

y(2-3xy)dx-xdy=0

Do you have any sample problem in solving for the angle of rotation in the deflection of the beam at any point using area moment method? Thanks :)

The topic is Population Growth, Decay and Investment. Somebody show the comple solution please.

A city has been found to have a population that triples every four years. If the city's population is one million in 2010, how many people were there in 1990?

The answer is 4,116.

( PASAGOT NAMAN PO ASSIGNMENT LANG PO HINDI KO TALAGA MASAGOT,, SALAMAT NG MARAMI.)An automobile is to travel a distance from A to B of 540m in exactly 4seconds. The auto accelerates and decelerates at 1.8 m/s^2, starting from rest A to rest B find velocity, maximum speed.

the rod is 10ft long weighing 20lbs. if it revolves through one end at 2rps, find the total energy.
