Solving Basic Trigonometric Equations Involving Sine

WebMay 24, 2010 · STEP 1: Convert all sec, csc, cot, and tan to sin and cos. Most of this can be done using the quotient and reciprocal identities. STEP 2: Check all the angles for sums and differences and use the appropriate identities to remove them. STEP 3: Check for angle multiples and remove them using the appropriate formulas. WebSolving basic equations can be taken care of with the trigonometric R method. Consider the following example: Solve the following equation: \cos x - \sqrt {3}\sin x = 2. cosx− 3sinx = 2. Using the R method, this equation can be converted into \cos\left (x+\frac {\pi} {3}\right)=1. cos(x+ 3π) = 1. Now, we know that \cos0^ \circ=1 cos0∘ = 1.
