| Use linear approximation to estimate In(0.95). Recall that In(1) = 0. A runner on an elliptical track described by the equation x2/y24 = 900 runs at a constant speed

v where x and y are measured in metres. Standing at the origin, you must rotate your head at 1/10 radians per second to watch her as she crosses the finish line located on the x axis. How fast is she running?
