I have watched so many of your videos since I started college this past winter. I love them all but always forget to like them. Is there an easy button for me to click that will like all your videos? Your video lessons are awesome. Thank you.
remember the ryhme: abc bac cab a2 = b2 + c2 - 2(b)(c) Cos A (abc) b2 = a2 + c2 - 2(a)(c) Cos B (bac) c2 = a2 + b2 - 2(a)(b) Cos C (cab) NOW: to find Cos A: since its negative transferring to the left it becomes positive 2(b)(c) Cos A = b2 + c2 - a2 Cos A = b2 + c2 - a2 / 2(b)c) same pattern for solving Cos B, C (or when the 2nd angle is known THEN 180d - Angle A + B so simple, what do you think?
No problem, i signed up to your website as well and it is very useful so thank you for that, You just have a way to make maths seem fun and i actually enjoy learning maths when watching your videos so thank you so much!
Will you be uploading any tutorials over sum & difference formulas of cosine, sine, tangent? Or teaching about Pythagorean identities, and applying these formulas to verify equations, for example: cosx(secx-cosx) = sin^2x ??? Thanks.
Hi Swed, thank you for your kindness. I think I know the issue: I did the inverse sine of the unrounded fraction, 0.99528404... to get 84.4º. The student did the inverse sine of just 0.99. Best to not round along the way, whenever possible.
Got really frustrated yesterday with my huge wall of text in my book. None of it explained how to solve the problems, just buried the information in Jargon. Thanks for teaching me more in 4 minutes than my textbook has taught me in 3 days.
This nigga held my hand and dropped me off to pre cal
I AM SO THANKFUL FOR THIS ACCOUNT! My teacher is not very good at explaining and this is perfect to help me for my test tomorrow!!
Mr. President you taught me just now with this lesson something that I will use to change the world. Thank you.

I LOVE THIS MAN!THANKS TO HIM IM NOT FAILING. i would love to be in this class.
without you I would actually fail
remember the ryhme: abc bac cab
a2 = b2 + c2 - 2(b)(c) Cos A (abc)
b2 = a2 + c2 - 2(a)(c) Cos B (bac)
c2 = a2 + b2 - 2(a)(b) Cos C (cab)
NOW: to find Cos A: since its negative transferring to the left it becomes positive
2(b)(c) Cos A = b2 + c2 - a2
Cos A = b2 + c2 - a2 / 2(b)c)
same pattern for solving Cos B, C (or when the 2nd angle is known THEN 180d - Angle A + B
so simple, what do you think?
thank you so much, even tho maths in England is a bit different to maths in the US, this really helped me and i'm so thankful!
Carbiine thank you so much, happy it's helping you!

wow...the way the cosine rule was explained....amazing 💜👌

The white hair effect 😂
inverse sin.99 = 84.1???? I got what the girl said she got 81.89

Thank You🔥🔥.. Really Helpful God Bless!!🙏😇😇🎊🎊
Finally thanks dude
Thank you!!!! You're amazing!
for the law of sines,can you write the formula the other way round?
+yaymath is the cosine taken of the included angle between the two sides?

Where they actually on the White House?
Thanl you soo much this helped me soo much good channel 👍👍
I LOVE THIS THANK U SO MUCH
thanks a lot .. too helpful >> you are the best
Hahaha that dance tho 5:53
Thanks !!
wher two cames form we now that you user pthegerm therom where -2 came form
If this is trig for you then why is it geometry for me...?
There's more of it in Alg II, just wait :,)
mr yay math. could you please make a video about the law of tanget? thank you in advance.
hi that's the spirit
Obamath is cool👍
Patriotism, am I right?
this is cringe
