Forget it....how you expect to understand the basis of calculus (rates of change - tangents) without trig.

And as for hyperbolic functions....eh what?

I guess we can depend on immigrants for all our higher maths.

And don't epect to go back to the moon, much less mars without classical trigonometry.
