Review of Mathematical Concepts and Principles MAY MGA BAGAY NA DAP AT MO NG BALI KAN, P ARA MAUNAWAAN Y AO NG DARAANAN. DALANGI N KO ’Y I KAW AY HI NDI MADARANG, Y ARI TAY O DY AN, SA SENI O R HI GH I KA’Y GUGURANG! SCIENTIFIC NOTATION Change to Scientific Notation 1. 56 760 000 000 2. 0.0000000902 Change to Standard Notation Rules for Multiplication Multiply the coefficients Add the exponents Base remains 10 What is the product of.. Rules for Division Divide the coefficients Subtract the exponents Base remains 10 What is the quotient if you divide.. Rules for Addition & Subtraction Express the numbers as the same power of 10 Get the sum or difference of coefficient What is the sum of.. Subtract the 1 number from the 2 st nd number. TRIGONOMETRIC FUNCTIONS sine cosine tangent Evaluate. INVERSE TRIGONOMETRIC FUNCTIONS R = sin A R is a number representing the sine of A (given) A is missing (required) Determine angle A in degrees 1. sin A = 0.8090 2. cos A = 0.7600 TRIGONOMETRIC FUNCTIONS c – hypotenuse b – side opposite B and adjacent to A a – side opposite A and adjacent to B TRIGONOMETRIC FUNCTIONS Solutions for Oblique Triangles Law of Sines Law of Cosines Law of Sines Law of Sines AAS – 2 angles and 1 adjacent side ASA – 2 angles and the side between ASS – 2 sides and the adjacent Law of Cosines Law of Cosines SAS – 2 sides and the included angle SSS – all 3 sides Problem 1: Problem 2: Solve for the magnitude of angles A, B, and C. a = 34ft c = 18ft b = 20ft Quiz on Mathematical Principles and Concepts Express in standard SCIENTIFIC NOTATION. 1) 123 000 000 2) 0.0000008 3) 204.5 Express in STANDARD NOTATION.
