Related rates area of a triangle
WebThe first step in a related rates question is to determine how the quantities are related. You have the constant rate of change of the length of the sides of an equilateral triangle and are asked about the rate of change of the area. So the first question you should ask is "how is the side length of an equilateral triangle related to its area?" WebNo. When you take the derivative of both sides, only a constant added onto either side would = 0. If 1/2 was added to the right-hand side of the equation, it would = 0 in the derivative. However, because the 1/2 is a coefficient (and is being multiplied, not added), the 1/2 remains. This is shown in a derivative rule: d/dx [A * f (x)] = A * f' (x)
