comment Proof: Force always perpendicular and motion in a plane implies that the trajectory is a circle
@DanielV No I mean that the force which corresponds to $x''$ and $x'$ which corresponds to the velocity are perpendicular.

comment Real world applications of exponential function; continous case
Well that's clear. The point is just that I cannot assume that students are familiar with $\mathrm{e}$.

comment Real world applications of exponential function; continous case
@mookid Yes but thats for the case $b < 1$, it's a decay. I know there are many interesting (quasi-)continous examples with $b < 1$, but I didn't know any really interesting examples for $b > 1$ which are not discrete.

comment Reference for similarity tests for triangles
Thanks for nice link! However it would be better to have a book as a reference since I want to cite it. By the way the link is about congruence, my question was about similarity.
