Key Calculus Terms and definitions covered in this textbook

If u = v and w = z , then u + w = v + z

• Annual percentage yield (APY)

The rate that would give the same return if interest were computed just once a year

• Argument of a complex number

The argument of a + bi is the direction angle of the vector {a,b}.

• Difference of functions

(ƒ - g)(x) = ƒ(x) - g(x)

• Direction angle of a vector

The angle that the vector makes with the positive x-axis

• End behavior

The behavior of a graph of a function as.

• Equal matrices
