Apr9 comment Is $\frac{2^x}{4x+5}$ rational? The domain of x is not stated in the book. It just says circle the rational expression below. Apr9 asked Is $\frac{2^x}{4x+5}$ rational?

Dec8 asked Finding if a particle of a parametric equation is moving horizontally. Dec6 accepted Find slope of parametric equation Dec6 comment Find slope of parametric equation My only other question just to make sure I am doing it correctly as I am fairly new to parametric equations is that I just need to divide and nothing fancy with derivatives right? Dec6 comment Find slope of parametric equation @Amzoti Yeah I just rechecked my work and saw I switched it out of the blue for some reason. Thanks for spotting that. Dec6 comment Find slope of parametric equation Thanks, this should help me along the right path. Dec6 asked Find slope of parametric equation Dec5 accepted Approximating Integral Dec5 accepted Position of Particle; When is it parallel to x-axis. Dec5 comment Approximating Integral @AndreySokolov As the graph of f(x) will be negative until x=-1. Thanks for spotting that. Which should put my answer at 1.707
