A particle is moving along the curve below. y= root(x)
As the particle passes through the point (4,2), its x-coordinate increases at a rate of 3 cm/s. How fast is the distance from the particle to the origin changing at this instant?
I appreciate the help
very good. when it comes to related rates, always draw a diagram if possible. as you can see, drawing that diagram allowed us to come up with Pythagoras' theorem as a way to relate the variables. if we had not drawn the diagram, we would probably not have known we were dealing with a triangle. so drawing the diagram is a good way to come up with what equation we should use, so remember that
