The most important part of MATH 1554 linear algebra is calculating the output vector of a Leontief model. Yep, Leontief models. Just ignore all that eigenvalue stuff and skip straight to the Leontief section. We must use row reduction, the chaddest method of solving linear systems in MATH 1554 linear algebra in order to solve the Leontief problem. You have a problem with Leontief? Go back to precalculus you dummy. The most important part of MATH 2551 multivariable calculus is calculating the volume of an ice cream cone. Yep, ice cream cones. Just ignore all that partial derivative stuff and skip straight to the ice cream cone section. We must use spherical coordinates, the chaddest coordinate system in MATH 2551 multivariable calculus in order to solve the ice cream cone problem. You have a problem with ice cream cones? Go back to single variable calculus you dummy.
