YACT: yet another calc thread

[Fenixgoon]

having trouble with related rates. i can never do triangle related rates when the rate is in term of the angle (whic is what i happen to have right here).

let alpha = angle BAC in triangle ABC with AB = c and AC =b, where b and c are constants and c > b. side BC changes length as alpha changes. find the rate of change of the area when alpha = pi/3. assume rate of change of alpha is 2

Thanks in advance
