Determining the triple angle of cosine to solve the equation

👉 Learn how to solve trigonometric equations. There are various methods that can be used to evaluate trigonometric equations, they include by factoring out the GCF and simplifying the factored equation. Another method is to use a trigonometric identity to reduce and then simplify the given equation. Simpler trigonometric equations involving one trigonometric function can simply be solved by inverse operations.
When solving a trigonometric equation it is usually useful to identify which method best evaluates the given equation and apply the method. Because trigonometric functions are sinusoidal in nature (continuous and repetitive), a trigonometric equation may contain many solutions depending on the domain of consideration.
When the trigonometric equation involves multiple angles, the trigonometric equation is evaluated first, and then the multiple of the angle is then divided through the obtained answer.

привет, Брайан, чувак. не поверишь, щас сижу в два ночи делаю дз по алгебре, и ты мне даже немного помог..!) THANK U, my american friend...

Your awesome im definitly subscribed

[@georgecortes197]

Thank you so much for this gem

[@jeremygraham7976]

This dude is fuckn awesome

Why is it add +2pi at 2:32?

[@noahsanchez5329]

to find all the solutions

[@aidancollins1591]

Because there is an infinite amount of solutions for the equation. You can just keep going around the circle over and over and over again until you reach infinity. To account for this, we write +2pi to signify all solutions.
