  Pre-Calculus   - Term 2 Assignment  –    Ms. Han shan@daltonschool.kr HS Room 214 INTEREST PACKET Exponential and Logarithmic Functions; Trigonometric Functions Students will study a class of functions called exponential functions. Exponential functions are used in modeling many real-world phenomena, such as the growth of a population or the growth of an investment that earns compound interest. Once an exponential model is obtained, we can use the model to predict population size or calculate the amount of an investment for any future date. Students will also study the trigonometric functions using the unit circle. The trigonometric functions can be defined in two different but equivalent ways: as functions of real numbers or as functions of angles. Students will study both approaches to solve different applications that require different approaches.

Stewart, L. Redlin and S. Watson,  Precalculus: Mathematics for Calculus, Sixth Edition . (2012: Cengage Learning, Belmont, CA) Skills Mastery Check  Interpreting Functions    Graph exponential and logarithmic functions, showing intercepts and end behavior, and trigonometric functions, showing period, midline, and amplitude. (10.IF.7.e)    Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions). (10.IF.9)  Building Functions    Understand the inverse relationship between exponents and logarithms and use this relationship to solve problems involving logarithms and exponents. (10.BF.5)  Linear, Quadratic, and Exponential Models    Prove that linear functions grow by equal differences over equal intervals, and that exponential functions grow by equal factors over equal intervals. (10.LQEM.1.a)    For exponential models, express as a logarithm the solution to abct = d where a, c, and d are numbers and the base  b is 2, 10, or e; evaluate the logarithm using technology. Interpret expressions for functions in terms of the situation they model. (10.LQEM.4) Trigonometric Functions    Understand radian measure of an angle as the length of the arc on the unit circle subtended by the angle. (10.TF.1)    Explain how the unit circle in the coordinate plane enables the extension of trigonometric functions to all real numbers, interpreted as radian measures of angles traversed counterclockwise around the unit circle. (10.TF.2)    Use special triangles to determine geometrically the values of sine, cosine, tangent for p/3, p/4 and p/6, and use the unit circle to express the values of sine, cosines, and tangent for x, p + x, and 2p  –   x in terms of their values for x, where x is any real number. (10.TF.3)    Choose trigonometric functions to model periodic phenomena with specified amplitude, frequency, and midline. (10.TF.5)    Understand that restricting a trigonometric function to a domain on which it is always increasing or always decreasing allows its inverse to be constructed. (10.TF.6)    Use inverse functions to solve trigonometric equations that arise in modeling contexts; evaluate the solutions using technology, and interpret them in terms of the context. (10.TF.7)    Prove the Pythagorean identity sin2(x) + cos2(x) = 1 and use it to find sin(x), cos(x), or tan(x) given sin(x), cos(x), or tan(x) and the quadrant of the angle. (10.TF.8)    Use the Law of Sines to solve triangles and understand which cases are ambiguous and which cases are unambiguous. (10.TF.9)    Use the Law of Cosines and use Heron ’ s Formula to find the area of a triangle.
