Trigonometric Function Conversion to Identity: Indeterminate Constraint Handling 1. MODULE: I 2. ORGANIZER: Pasti Menang 3. SOFTWARE: Maple 13 4. OBJECTIVES: Students can understand the concept of limit function in problem-solving and students are expected to be able to calculate the limit value of a trigonometric function both manually and computationally using Maple 13 software. 5. INTRODUCTORY THEORY a. Concept of Limit of Trigonometric Functions A trigonometric limit is the closest value to an angle of a trigonometric function. Calculation The limit of this function can be directly substituted as for example the limit of an algebraic function but there is a trigonometric function that must first be converted to a trigonometric identity for an indeterminate limit, namely a limit that if directly substituted the value is 0, it can also be for an indeterminate limit does not have to use identity but uses the trigonometric limit theorem or some use identity and theorem. So if a trigonometric hifunction is substituted for a value that approaches it produces and then it must be solved in another way. To get started with the concept of trigonometric function limits, consider the table of values and graph of the function f(x) = sin x below. c. How to Solve Limit Trigonometric Functions First, the limit problem of trigonometric functions can be solved by substituting Direct. If the result obtained is not an indeterminate form 0/0, then the result is the limit value sought. If the result is an indeterminate form 0/0, then you can use substitution, the basic formula for the limit of trigonometric functions, factoring, simplifying it, and multiplying by a pair.
