    Related Rates Question

    Hello,

    I'm having trouble with this related rates problem:
    Two sides of a triangle are 4m and 5m in length and the angle between them is increasing at a rate of 0.06rad/s (radians per second). Find the rate at which the area of the triangle is increasing when the angle between the sides of fixed length is pi/3.

    A = \frac{1}{2} ab \sin{\theta} , where a and b are the side lengths and \theta is the angle between them.

    sub in your constants and take the time derivative ...
