The two curves y = 3 and y = 5 intersect at an angle
A.
Given curves y = 3x ...(i)
and y = 5x ...(ii)
Intersect at the point (0, 1).
Now, differentiating Eqs. (i) and (ii) w.r.t. x, we get
The length of the shadows of a vertical pole of height h, thrown by the sun's rays at three different moments are h, 2h and 3h. The sum of the angles of elevation of the rays at these three moments is equal to
