Expanding isosceles triangle The legs of an isosceles right tri-
angle increase in length at a rate of 2 m/s.
a. At what rate is the area of the triangle changing when the legs
are 2 m long?
b. At what rate is the area of the triangle changing when the hypot-
enuse is 1 m long?
c. At what rate is the length of the hypotenuse changing?
