x a can make f ( x ) arbitrarily large (and positive) by taking x sufficiently close to a (on either side of a) without letting x = a . There is a similar definition for lim f x a ( x ) = - except we make f ( x ) arbitrarily large and negative. Graph is a line with point (0; b) and slope m. Graph is a circle with radius r and center (h; k). a2 b2 Graph is an ellipse with center (h; k) with vertices a units right/left from the center and vertices b units up/down from the center. The graph is a parabola that opens up if a > or down if a < 0 and has a vertex at (h; k). center with slope . In this section, we describe a general technique for solving first-order equations. We begin with linear equations and work our way through the semilinear, quasilinear, and fully non-linear cases. We start by looking at the case when u is a function of only two variables as that is the easiest to picture geometrically. To write algebraic expressions and equations, assign a variable to represent the unknown number. In the table below, the letter x is used to represent the unknown. In translation problems, the words sum, total, difference, product and quotient imply at least two parts use parentheses when a sum or difference is multiplied. The reader should check that for the perturbation of the right-handsidebusedearlier,therelativeerrorsx/x and x/x satisfy the inequality x x cond(A) b b and comes close to equality. These can be derived from the definition of ln x as the inverse of the function ex, the definition of e, and the rules of exponents we reviewed at the start of lecture. For example, suppose X represents the roll of a fair 6-sided die, and Y represents whether the roll is even (0 if even, 1 if odd). Clearly, the value of Y tells us something about the value of X and vice versa.
