That's OK, we can understand you perfectly. Especially with your nifty picture.
Why did the vector cross the road?
It wanted to be normal.
while its not necessary here, you can also use derivatives to help you find the point of tangency of a line tangent to a circle (or any differentiable function). If you know the slope of the line its tangent to. Sometimes it can speed things up.

A logarithm is just a misspelled algorithm.
