x^y=e^x-y Taking log both side ylogx = x-yloge (loge=1) ylogx = x-y Differentiate both side w.r.t x y/x + logx dy/dx = 1 - dy/dx dy/dx(logx+1)= 1-y/x dy/dx = x-y/x(logx+1) = ylogx/x(logx+1) = logx/(logx+1)^2 ANSWER

Given : x^y=e^x-y taking log both side we get, ylogx =(x-y)loge=(x-y). .....1 when x=1 then y(log1)=(1-y)=y=1 Differentiate both side w.r.t 'x' y(1/x)+logx dy/dx = 1-dy/dx =dy/dx ( logx +1) = 1 - y/x = dy/dx = x-y/x(logx +1) when x=1 then, dy/dx= 1-1/1(log1+1) = 0

37. The traffic police has installed Over Speed Violation Detection (OSVD) system at various locations in a city. These cameras can capture a speeding vehicle from a distance of 300 m and even function in the dark. A camera is installed on a pole at the height of 5 m. It detects a car travelling away from the pole at the speed of 20 m/s. At any point, x m away from the base of the pole, the angle of elevation of the speed camera from the car C is θ. On the basis of the above information, answer the following questions : (i) Express θ in terms of height of the camera installed on the pole and x.
