This lesson will provide examples and explain how to solve trigonometric functions while applying this knowledge to solve trigonometric equations.
Calculus I: Lesson 14: Solving Trigonometric EquationsDr. Karen Brucks
Trigonometric Equations In this video lesson, we talk about trigonometric equations. What are they? Remember your basic trig functions of sine, cosine, and tangent? Well, your trigonometric equations are simply equations that include trig functions. For example, the equation sin x = 1 is an exam...
Identify all exact solutions to the equation 2(tanx+3)=5+tanx,0≤x<2π2(tanx+3)=5+tanx,0≤x<2π. Show Solution Solving Trigonometric Equations in Quadratic FormSolving a quadratic equation may be more complicated, but once again, we can use algebra as we would for any quadr...

Some equations are true for all allowed values and are then called IdentitiesExample: sin(−θ) = −sin(θ) is one of the Trigonometric Identities Let's try θ = 30°: sin(−30°) = −0.5 and −sin(30°) = −0.5 So it is true for θ = 30° Let's try θ = 90°...
Precalculus Module 9: Trigonometric Identities and Equations Search for: Problem Set 51: Solving Trigonometric Equations With Identities1. We know g(x)=cosxg(x)=cosx is an even function, and f(x)=sinxf(x)=sinx and h(x)=tanxh(x)=tanx are odd functions. What about ...
In summary, the conversation discusses finding invariant points between a base trigonometric function and a horizontally stretched function. The only invariant point for a horizontal stretch is when x = 0, as all other points on the graph are affected by the transformation. ...
