90 Extrema and the Geometric Applications of a Derivative [Ch. 3 878. A point M (x , # ) lies in the first quadrant of a coordinate plane. Draw a straight line through this point so that the triangle which it forms with the positive semi-axes is of least area. 879. Inscribe in a given ellipse a rectangle of largest area with sides parallel to the axes of the ellipse. 880. Inscribe a rectangle of maximum area in a segment of the parabola y* = 2px cut off by the straight line x = 2a. 881. On the curve y = - , t find a point at which the tangent 1 -\- X forms with the A>axis the greatest (in absolute value) angle. 882. A messenger leaving A on one side of a river has to get to B on the other side. Knowing that the velocity along the bank is k times that on the water, determine the angle at which the messenger has to cross the river so as to reach B in the shortest possible time. The width of the river is h and the distance between A and B along the bank is d. 883. On a straight line AB=a connecting two sources of light A (of intensity p) and B (of intensity
Sec. 2]_The Direction of Concavity. Points of Inflection 91 887*. The centres of three elastic spheres A, B\ C are situated on a single straight line. Sphere A of mass M moving with velocity v strikes fi, which, having acquired a certain velocity, strikes C of mass m. What mass should B have so that C will have the greatest possible velocity? 888. N identical electric cells can be formed into a battery in different ways by combining n cells in series and then combining the resulting groups (the number of groups is allel. The current supplied by this battery is given by , ~~ NnS ] in par- the formula where < is the electromotive force of one cell, r is its internal resistance, and R is its external resistance. For what current? value of n will the battery produce the greatest 889. Determine the diameter y of a circular opening in the body of a dam for which the discharge of water per second Q will be greatest, if Q = cy Vhtj, where h is the depth of the lowest point of the opening (h and the empirical coefficient c are constant). 890. If x lf # 2 , ..., x n are the results of measurements of equal precision of a quantity x, then its most probable value will be that for which the sum of the squares of the errors 0=2 (*-*,) 1=1 is of least value (the principle of least squares). Prove that the most probable value of x is the arithmetic mean of the measurements. Sec. 2. The Direction of Concavity. Points of Inflection 1. The concavity of the graph of a function. We say that the graph of a differentiable function y f(x) is concave down in the interval (a,b) [concave up in the interval (ap 6,)] if for a
