The cross-section of the rotor blade of a helicopter contains a particular angle θ. The area of the cross-section is given by A = 1/4 sin 2θ + sin^2θ Find the maximum area of the cross-section, and the smallest positive value of θ when this maximum occurs. Give the angle θ as an exact value (using an inverse trig function), then use a calculator to give an approximation (use degrees) without calculas
