wliia (03/09/2014) [] Well, technically a tangent like can cross at multiple points. For example in the graph to the right the tangent line passes through the graph twice. A tangent line is not a line that crosses a function once. A better way of explaining it would be to imagine the tangent line crossing the curve at point P would be to define point Q as any other point on the curve. The secant line joining point P and point Q would become the tangent line when Q is brought to and is point P.
So a tangent line could possible cross a line an infinite number of times (An easy example would be either tangent line with slope = 0 on either the sin or the cos functions.)

parallel lines meet in infinity...

You speak as if that was an actual existing thing, rather than just a pure definition. In Euclidean geometry its an axiom that they don't intersect. In proyective geometry, the fact that they intersect in infinity is also by definition.

In Euclidean geometry, no. And given the fact that Euclidean geometry is the only **** students learn unless they study mathematics at the university, it's not education "suck[ing] that bad." It's that people like you learn a fun detail like that, but have absolutely no understanding of the context.
