Solving Trigonometric Equation, Harder Example - Example 1

[DoctorHadez]

thank you so much 7 years later and this still helps me

[ryankbr]

loved this explanation! it was so much better than my professor's lecture, thanks so much!

[newtocamelot]

Oh my god, i love you! My teacher was trying to explain this to me today but your way of expaining is so much easy to understand

[saf]

Oh my gosh thank you for explaining this so clearly! Wish I could have you as my lecturer! (instead of my current one who criticises and shouts at us ugh)

[EsspressoStresso]

most people don't know how to explain this really well, but you did.  Thanks! :)

THANK YOU THANK YOU THANK YOU! the only video that addressed my issue!

[BlondeRedheadislove]

Your videos have helped me so much over the years. I think this is my first comment on them, but it's so hard to hear you in this video. :(

[hugooscarbanchieri]

Thank you so much for this explanation.
It was so clear!
Could you help me with this one:

Thank you very much!

is there any way to work out the number of solutions in a general case? like the number of solutions for A.sin(B.x+C)+D=0 where A, B, C, D are random constants within the range of [-10, 10]. This is for developing a computer aided assessment for my university final year project. Thanks in advance!

[asimupreti]

For the same problem can there be two different solutions ? Plz respond !!!

[sonju]

How did you get 5pi/3 after the pi/3? I don't get how you get it?

[htoor]

if your looking for the general solution cant you just do pi/3 + 2pi(k), where k equals all real integers

[victoriagainey]

In the first problem, why do you add 2pi if there if a restriction?

my teacher tried to teach us this in 2 days but i still dont get it. She said something about finding the period in order to know how many solutions we have to find, but I dont understand how. Then she solved this problem: tan(3x)=1 and I thought you had to draw the triangle in QI and QIII so Tangent would be positive, but she only did it w/QI, y? Please help me

[tajbibishamim]

Why have you not done same with -1/2 solution?

[kentrader]

I think keeping the solutions + 2(pi)(n) is more accurate because it accounts for the infinite cycles

[EntertainYourselfTV]

wouldnt 5pi/3 be for negative have cuz its on the left side of the unit circl and on the left side cos is negative... im confused... plz someone explain this to me

[whitefang]

Why was everything multiplied by 1/2 at the end?

[vlogzzbytasfiyah]

I'm still so confused omg I'm going to fail my finals

[TheMonsterMichael]

Couldn't you just use a half angle identity?
