A small ball is projected with speed 15 m/s at an angle of 60 degrees above the horizontal. Find the distance from the point of projection of the ball at the instant when it is travelling horizontally.

If we break down the velocity vector into its x and y components, then the point at which the ball would be moving horizontally is the point where the y velocity is zero. The y velocity decreases initially d...

Explain why for any constant a, if y = a^x then dy/dx = a^x(ln(a))

So let's start with taking the natural log on both sides of y=a x , giving us ln(y) = ln(a x ). Using the laws of logarithms we can write this as ln(y) = xln(a).Next, we differentiate both sides with respect...
