AAAAAAA, LEAVE 4/81 as a FRACTION, You will contaminate the EQUATION. Is no one else bothered by this?

[@jonathanhele0886]

Thankyou that's very clear!

[@mikei6605]

worked! thank you this was a help. I forgot it was cos-1 tho

[@topgpe]

you always have to use cos-1 if you want to find an angle

[@dongertan3320]

Thanks for this video sir.

[@robloxmaster2096]

I love the way u explain this but the triangle doesn’t always have to be named ABC so what I shall do in this case 😢

[@BritxTalyaa]

[@zactatonetti6442]

Legend.

[@minyngi3319]

Yeshhshshs Finally I can do math work

[@jamesbutton5036]

cos-1(0.0476) on my Casio was coming up with 1.523178333??? might my calculator be broken or something?

[@topgpe]

have you got the right settings active????

[@ravenstinson8318]

You must have had it on RAD instead of DEG mode

The writings of the speech on the screen tend to block the view of those of us who follow the tutorials online.

[@parvinzaman5863]

I really cant hear you please fix that other than that thank you so much ♡♡♡

[@voldy3565]

What if I don't know big C or small c?

[@skywasfound6371]

small are sides big are angles

[@franciscoprieto1534]

This guy looks like David Gahan from Depeche Mode.

[@tizianorosso3288]

whats your name?

[@re5had390]

Nice

[@casandraogrady5793]

It's meant to be Cos B equals 7squared plus 6squared - 9squared divided by 2 x 7 x 6? Cos B equals 49 plus 36 - 81 divided by 85 Cos B equals 4 divided by 85 0.047 and so on ...

[@ajnabiatrab9481]

thanks for the video but I need. a video where u will tell us when to use which formula of cosine rule plzzzzz

[@moallam7685]

no 14 x 6 = 84 not 85

[@aliceyoon9048]

Come backkk ;((

[@omomar56]

I got 61.57

[@ssb_kirito4056]

bruh wat 7 square + 6 square = 85 howd yu get 49….

[@thexforo]

Only 7 squared is 49

[@funitoo]

and again... no mention of what Cos is... useless

Tad Ka this is higher trigonometry, you shouldn’t be looking here for what trigonometric ratios are. try typing this: Trigonometric Ratios.
