Find the Exact Solutions of the Given Trigonometric Equation Solve the following equation : sin θ + sin 3θ + sin 5θ = 0. Solution : sin θ + sin 3θ + sin 5θ = 0. First let us use the formula for sin C + sin D. 2 sin 3θ cos 2θ + sin 3θ = 0. sin 3θ (2cos 2θ + 1) = 0. sin 3θ = 0 (or) 2cos 2θ + 1 = 0 Solving A Log Equation The purpose of solving a logarithmic equation is to find the value of the unknown variable. In this article, we will learn how to solve the general two types of logarithmic equations, namely: ... Given the equation; log 3 (x 2 + 3x) = log 3 (2x + 6), drop the logarithms to get; => x 2 + 3x = 2x + 6 => x 2 + 3x - 2x - 6 = 0.

Solving for the unknown math worksheets. Bearing - Word Problems | Brilliant Math & Science Wiki Let the horizontal distance between the helicopter and the island be d d, and the width of the island w w. Then \tan 24^\circ = \frac {1000} {d+w} tan24∘ = d+w1000 and \tan 31^\circ = \frac {1000} {d} tan31∘ = d1000, implying d = \frac {1000} {\tan 31^\circ} d = tan31∘1000. The Learning Portal: Math: Basic Tutorials: Proportions Line 1: Set up the problem as equivalent fractions and let x represent the unknown number of hours. 1.5 hours over 4 pages equals x hours over 15 pages. Line 2: Cross multiply, which means to multiply the numerator of the fraction on the left by the denominator of the fraction on the right, and multiply the numerator of the fraction on the right by the denominator of the fraction on the left. 4x equals 2 times 15. › algebraAlgebra Worksheets - Math-Drills Welcome to the Algebra worksheets page at Math-Drills.com, where unknowns are common and variables are the norm.
