How To Solve Trigonometric Equations Include All Solutions Simple This trigonometry video tutorial explains how to solve trigonometric equations by factoring and by using double angle formulas and identities. it explains h. 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. 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.

Unit 4: trigonometric equations and identities. 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. Analysis. we can see the solutions on the graph in figure 3.on the interval 0≤θ<2π,0≤θ<2π, the graph crosses the x axis four times, at the solutions noted.notice that trigonometric equations that are in quadratic form can yield up to four solutions instead of the expected two that are found with quadratic equations.
