Name_____________ Show all your work for full credit. Use the space provided below. 1. A particle moves along the curve y = 1 + x3 . As it reaches the point (2, 3), the y-coordinate is increasing at a rate of 4 cm/s. How fast is the xcoordinate of the particle changing at that instant? 2. Two sides of a triangle have lengths 12 m and 15 m. The angle between them is increasing at a rate of 2D / min . How fast is the length of the third side changing when the angle between the sides of fixed length is 60D ?
