The derivative is the quotient rule where f(x) = g(x)/h(x) where g(x) = 2009^x and h(x) = x^2009. g'(x) = ln(2009)2009^x and h'(x) = 2009x^2008. The derivative is (lo d hi - hi d lo)/lo². This

The length of the rod is 1200 cm. The radius of the wheel is 40 cm. Draw a ling (or picture a line) from A that is perpendicular with the x-axis. The length of this vertical line is 40•sin(Θ)

2009-11-05 Lines tangent to ellipse:

Let's suppose that the point where the tangent line touch the ellipse is (xo,yo). We can find a relation between xo %26 yo, by substituting (xo,yo) in the equation of the ellipse : (xo²/4)+(yo²/9)=1

The volume V(t) is equal to the side s(t) to the third. That is, V(t) = s³(t). Given this, the change in volume is dV/dt = 3s²(t)(ds/dt). We are given that dV/dt = 2, so 2 = 3s²(t)(ds/dt). That
