The area of a triangle with sides of lengths a and b containing angle theta is = 1/2absin(theta).  A. if a = 2cm and b = 3cm and theta increases at a rate of .2 rad/min, how fast is the area increasing when theta = pi/3? B. if a = 2cm and b increases at a rate of 1.5 cm/min, and theta increases at a rate of .2 rad/min, how fast is the area increasing when b = 3cm and theta = pi/3? C. if a increases at a rate of 2.5cm/min, b increases at a rate of 1.5cm/min and theta increases at a rate of .2 rad/min, how fast is the area increasing when a = 2cm, b = 3cm, and theta = pi/3?
