POLAR COORDINATES AND COMPLEX NUMBERS 


2014 Indiana Academic Standards 
Activities, Examples, or Resources 
PC.PCN.1: Calculate the distance between numbers in the complex plane as the modulus of the difference, and the midpoint of a segment as the average of the numbers at its endpoints. 

PC.PCN.2: Understand and use complex numbers, including real and imaginary numbers, on the complex plane in rectangular and polar form, and explain why the rectangular and polar forms of a given complex number represent the same number. 

PC.PCN.3: Understand and use addition, subtraction, multiplication, and conjugation of complex numbers, including real and imaginary numbers, on the complex plane in rectangular and polar form. 

PC.PCN.4: State, prove, and use DeMoivre’s Theorem. 

FUNCTIONS 


2014 Indiana Academic Standards 
Activities, Examples, or Resources 
PC.F.1: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity. 

PC.F.2: Find linear models by using median fit and least squares regression methods. Decide which among several linear models gives a better fit. Interpret the slope and intercept in terms of the original context. 

PC.F.3: Recognize that sequences are functions, sometimes defined recursively, whose domain is a subset of the integers. 

PC.F.4: Determine if a graph or table has an inverse, and justify if the inverse is a function, relation, or neither. Identify the values of an inverse function/relation from a graph or a table, given that the function has an inverse. Derive the inverse equation from the values of the inverse. 

PC.F.5: Produce an invertible function from a noninvertible function by restricting the domain. 

PC.F.6: Describe the effect on the graph of replacing f(x) by f(x) + k, k f(x),f(kx), and f(x + k) for specific values of k (both positive and negative). Find the value of k given the graph f(x) and the graph of f(x) + k, k f(x), f(kx), or f(x + k). Experiment with cases and illustrate an explanation of the effects on the graph using technology. Recognize even and odd functions from their graphs and algebraic expressions. 

PC.F.7: Decide if a function is continuous at a point. Find the types of discontinuities of a function and relate them to finding limits of a function. Use the concept of limits to describe discontinuity and endbehavior of the function. 

PC.F.8: Define arithmetic and geometric sequences recursively. Use a variety of recursion equations to describe a function. Model and solve word problems involving applications of sequences and series, interpret the solutions and determine whether the solutions are reasonable. 

PC.F.9: Use iteration and recursion as tools to represent, analyze, and solve problems involving sequential change. 

PC.F.10: Describe the concept of the limit of a sequence and a limit of a function. Decide whether simple sequences converge or diverge. Recognize an infinite series as the limit of a sequence of partial sums. 

QUADRATIC, POLYNOMIAL, AND RATIONAL EQUATIONS AND FUNCTIONS 


2014 Indiana Academic Standards 
Activities, Examples, or Resources 
PC.QPR.1: Use the method of completing the square to transform any quadratic equation into an equation of the form (x – p)^2 = q that has the same solutions. Derive the quadratic formula from this form. 

PC.QPR.2: Graph rational functions with and without technology. Identify and describe features such as intercepts, domain and range, and asymptotic and end behavior. 

PC.QPR.3: Know and apply the Remainder Theorem: For a polynomial p(x) and a number a, the remainder on division by x – a is p(a), so p(a) = 0 if and only if (x – a) is a factor of p(x). 

PC.QPR.4: Understand the Fundamental Theorem of Algebra. Find a polynomial function of lowest degree with real coefficients when given its roots. 

EXPONENTIAL AND LOGARITHMIC FUNCTIONS AND EQUATIONS 


2014 Indiana Academic Standards 
Activities, Examples, or Resources 
PC.EL.1: Use the definition of logarithms to convert logarithms from one base to another and prove simple laws of logarithms. 

PC.EL.2: Use the laws of logarithms to simplify logarithmic expressions and find their approximate values. 

PC.EL.3: Graph and solve realworld and other mathematical problems that can be modeled using exponential and logarithmic equations and inequalities; interpret the solution and determine whether it is reasonable. 

PC.EL.4: Use technology to find a quadratic, exponential, logarithmic, or power function that models a relationship for a bivariate data set to make predictions; compute (using technology) and interpret the correlation coefficient. 
PARAMETRIC EQUATIONS
