Evaluate double integral Z 2 0 Z 1 y/2 cos(x^2 )dx dy
(integral from 0 to 2)(integral from y/2 to 1) for cos(x^2) dx
dy

solve the differential equation...
(x2-1)(dy/dx)+xy=0

Evaluate the line integral by the two following methods.
(xy dx + x2 dy)
C is counterclockwise around the rectangle with
vertices (0, 0), (2, 0), (2, 1), (0, 1)
(a) directly
(b) using Green's Theorem

solve diffeential equation.
( x2y +xy -y )dx + (x2 y -2 x2)
dy =0 answer x + ln x + x-1 + y- 2 lny = c
dy / dx + 2y = e-2x - x^2 y (0) =3 answer
y = 3 e -2s + e-2x ( intefral of e
-s^2ds ) s is power ^ 2 means s to power of
2
