Trigonometry Solving Trig Equations Part 2 Youtube Lesson 7.5: solving trigonometric equations (special case) part 2this video explains how to solve a trigonometric equation when sine and cosine functions ar. 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. More practice. solving trigonometric equations is finding the solutions of equations like we did with linear, quadratic, and radical equations, but using trig functions instead. we will mainly use the unit circle to find the exact solutions if we can, and we’ll start out by finding the solutions from $ \left [ 0,2\pi \right)$. Now, in a calculus class this is not a typical trig equation that we’ll be asked to solve. a more typical example is the next one. example 2 solve 2cos(t) = √3 on [− 2π, 2π]. show solution. in a calculus class we are often more interested in only the solutions to a trig equation that fall in a certain interval.

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.
