Solve the problem.The strength S of a wooden beam with rectangular cross section is given by the formula S = kd3 sin2 ? cos ?where d is the diagonal length, ? the angle illustrated, and k is a constant that varies with the type of wood used. 
Let d = 1 and express the strength S in terms of the constant k for ? = 45°, 50°, 55°, 
and 65°. Does the strength always increase as ? gets larger?
