How To Solve Trigonometric Equations With Multiple Angles We solved so many equations when studying algebra. now that we understand trig functions, as well as inverse trig functions, we are ready to solve trigonomet. Example 3.3.3c: solving an equation involving tangent. solve the equation exactly: tan(θ − π 2) = 1, 0 ≤ θ <2π. solution. recall that the tangent function has a period of π. on the interval [0, π),and at the angle of π 4,the tangent has a value of 1. however, the angle we want is (θ − π 2). thus, if tan(π 4) = 1,then. A trigonometric equation is one that states a relation between trigonometric functions of unknown angles (or numbers) trigonometric equations, in general, have an unlimited number of solutions. usually the domain is restricted to 0 ≤ θ ≤ 360, to limit the number of solutions. no general method for solving equations can be given. Recall the rule that gives the format for stating all possible solutions for a function where the period is 2π: sinθ = sin(θ ± 2kπ) there are similar rules for indicating all possible solutions for the other trigonometric functions. solving trigonometric equations requires the same techniques as solving algebraic equations.

Know how to solve basic trig equations. there are 4 types of basic trig equations: sin x = a ; cos x = a; tan x = a ; cot x = a; solving basic trig equations proceeds by studying the various positions of the arc x on the trig circle, and by using trig conversion table (or calculator). to fully know how to solve these basic trig equations, and. 1 tan2θ = 1 (sinθ cosθ)2 rewrite left side = (cosθ cosθ)2 (sinθ cosθ)2 write both terms with the common denominator = cos2θ sin2θ cos2θ = 1 cos2θ = sec2θ. recall that we determined which trigonometric functions are odd and which are even. the next set of fundamental identities is the set of even odd identities.
