Solving a trigonometric equation by factoring

👉 Learn how to solve trigonometric equations. There are various methods that can be used to evaluate trigonometric equations, they include 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.

When solving a trigonometric equation it is usually useful to identify which method best evaluates the given equation and apply the method.

hey bro, 8 years later and you're still here saving us! whenever i'm struggling or having trouble with a concept, i can always rely on you to clear it up, and thats dope. thanks man!

[keithsimmons]

Taking trig online, and this is probably the 8th video of yours I've watched this semester that have made everything crystal clear. Thank you for what you do!

I know I'm late to the party, but I just want to say how much I appreciate you making the videos. I'm in college trig and you explain things so much clearly than my profs. Thanks

[KronkBH]

These videos are great refreshers to sleep on before a test. Thanks for all the uploads!

[elliot]

If you notice his small mistakes, you know the content. You’re gonna do great on your test tomorrow.

[faithisabel]

You're such a great teacher!
Thank you for posting this video.

So we have to memorize the unit circle to represent the answer in terms of the interval (0, 2pi)?

[redfish]

@Brian McLogan is it true that solving trigonometry sometimes ends up with extraneous solutions?

[mryup]

I love this guy as a teacher! Always there when I need help and not at school.

[shenelldixon]

that's like the easiest trig factoring. thank

[joeygojcaj_]

U saved my life math wise brotha, really appreciate that

[fariddolabani]

You are king at explaining math thank you so much. This helped me a lot

[DailyMotivator]

Thanks for helping me! This question was on my test

[IsaacRobertoCordova]

Thank you so much, sir! It really helps me before preparing for College Precalculus. 🙏🏻😁

Quick tip: if you have inverse functionality on your calculator eg sin-¹(x) you can skip the unit circle step

[guillermovazquez]

I've always had weak arithmatic. Thanks for existing to make things easier

Hi! If the coefficient was 4 instead of 2 how would you know when to factor it as "(4sinx+1)(sinx+1)" and not (2Sinx+1)(2Sinx+1)"








Thanks!

[AniMorcito]

what do i do if my x=1/3 and x=2 cause those arent on the unit circle

[hhitntf]

Hey Sir...How can you solve for 2sin A+3 COSA =0
