    Page 21 21 3.1 Scientific Calculations The scientific functions can be used either with BASIC programs or for manual calculations. For the sake of the explanation, all the examples here will cover only manual calculations. 3.1.1 Trigonometric and Inverse Trigonometric Functions SIN (Sine), COS (Cosine), TAN (Tangent), ARCSIN (Arc Sine), ARCCOS (Arc Cosine), ARCTAN (Arc Tangent). These functions return a trigonometric function value for a given angle, or an angle value of a given trigonometric function value....

Three different keys are used when working with the formula Storage function. IN key……. Stores presently displayed formula. OUT key…… Displays formula stored in memory. CALC key…. Assigns values to variables in formula, and displays formula calculation result. Sample Application EXAMPLE: Obtain the value for each of the value assigned to x when y = 3.43 cosx. (Calculate in three decimal...
