Personally I felt that Calculus was basically advanced algebra with some special sauce.
Algebra: m = ?y/?x
This only works with lines though; then bam Calculus makes this thingy and it works with everything. EVERYTHING*.
Calculus: m = ?y/?x = ?f(x)/?x = (f(x1) - f(x))/(x1-x) ::: x1 = x+h ::: (f(x+h) - f(x)) /(x+h-x) ==== (f(x+h) - f(x))/(h)
*Not really everything.
Yeah ditto.
Geometry was my only math class that I didn't feel was an expanson of algebra.
