If the area of the parallelogram with as two adjacent sides is 15 sq unit, then the area of the parallelogram having and as two adjacent sides in sq unit is :
120
105
75
45
is equa to :
C.
The area enclosed between the parabola y = x2 - x + 2 and the line y = x + 2 in sq unit equals :
The solution of the differential equation e-x(y + 1)dy + (cos2(x) + sin(2x))y dx = 0 subjected to the condition that y = 1 when x = 0 is
y + log(y) + excos2(x) = 2
log(y + 1) + excos2(x) = 1
y + log(y) = excos2(x)
(y + 1) + excos2(x) = 2
