This is not all; the calculation of powers and roots can be simplified with the use of logarithms. Near the angle θ=0, cos(θ) is very close to 1. MATHS: Trigonometry & Logarithms - Marcus Du Sautoy. Given a sum, difference, or product of logarithms with the same base, write an equivalent expression as a single logarithm. A Treatise on Trigonometry, and on Trigonometrical Tables and Logarithms; Together with a Selection of Problems and Their Solutions: Hymers, John: Amazon.sg: Books For problems 4 – 6 write the expression in exponential form. Trigonometry Word Problems Worksheet with Answers - Concept - Problems with step by step answers. Recall from above that , where P is the initial investment (principal), r is the interest rate, and V is the value of the investment at time t (expressed in years).
