Between Rational and Irrational
Economists have generally understood human behavior as either rational (the classical model) or irrational (the behavioral model). Robb argues instead for a third framework, the type of decisions that we do for their own sakeβbehavior...

Finding the Slant Asymptote
π Learn how to find the slant/oblique asymptotes of a function. A slant (oblique) asymptote usually occurs when the degree of the polynomial in the numerator is higher than the degree of the polynomial in the denominator. To find the...
