Tip: Use the change of base formula to = = → = convert to base 10 (log) or base e (ln). Some calculators handle only these = = + bases. √. Tutorials page.
Distance Formula Given two points, P A = (x 1;y 1) and P B = (x 2;y 2), the distance between the two can be found by: d(P A;P B) = p (x 2 x 1)2 + (y 2 y 1)2 Number Classi cations Natural Numbers : N=f1, 2, 3, 4, 5, . . .g Whole Numbers : f0, 1, 2, 3, 4, 5, . . .g Integers : Z=f... ,-3, -2, -1, 0, 1, 2, 3, .. .g Rationals : Q= All numbers that ...
