## Main Question or Discussion Point

hey all

can anyone explain why, for small [itex] \alpha[/itex] we may allow [itex] \tan \alpha = \alpha[/itex] at an intuitive, geometrical perspective. i already understand the series explanation and higher order of tangent. im just trying for a picture.

thanks!
