A body cools in a surrounding which is at constant temperature of `theta_(0)`. Assume that it obeys Newyon's law of colling. Its temperature `theta` is plotted against time `t`. Tangents are drawn to the curve at the points `P(theta=theta_(t))` and `Q(theta=theta_(2))`. These tangents meet the time axis at angles of `phi_(2)` and `phi_(1)`, as shown
