Let I be the purchase value of an equipment and V(t) be the value after it has been used for t years. The value V(t) depreciates at a rate given by differential equationd V(t)/dt = - k(T - t), where k > 0 is a constant and T is the total life in years of the equipment. Then the scrap value V(T) of the equipment is

The area bounded by the curve y = cos x and y = sin x between the ordinates x = 0 and x = 3π/2 is
A.
Solution of the differential equation
cos x dy = y (sin x - y) dx, 0 < x < π/2, is
sec x = (tan x + C ) y
y sec x = tan x + C
y tan x = sec x + C
y tan x = sec x + C
