This is a genital trick which is sure to entertain your grandma or any passers by in the street. This should only be tried if you are very confident of the size of your "garbage" and your timing, as these are both essential for the trick. First get naked. Good. Then stand with your legs astride, then thrust you pelvis so your genitals flick back and forth. Then, on the backswing shut your legs and lean forward so your genitals are between your legs and on the otherside of your body, and you've done it. Once done, this moves has two hillarious sides to it, from behind you look slightly deformed and a bit like your shitting your own balls. Also, from the front it looks like you have no willy so is a short term alternative to a sex change, use a knife for more permanent consequences. However beware of the dire consequences of getting your timing wrong and totally caining yourself by squishing your balls in between your legs, so watch it.

The method used to get the gradient of the normal line to a point on a curve by using the gradient of the tangent at that point. Therefore reversing the sign (+/-) and flipping the fraction.
Hey doode I just got the gradient of the normal at (4,5) to this curve by switching the gradient from -(4/1) to +(1/4). I am totally gonna flip reverse it again
