Introduction to Trigonometric Functions

[securezone]

great video. better than KhanAcademy! you rock.

[VampiresRule012]

who else smiled and rolled their eyes when he said "or hyp... for hypotenuse"? xD

[TheDeadlySatan]

thank you so much! This is what I need for My Project! Keep it up! :)

[ServingAlmighty]

Wow! You rock! Thanks

[superawesomedude107]

He filmed this on Monday :)

[OfficialEasymusic]

Damn bro I actually got this, trig. is not that hard actually just hard formula's man but you explained it good bro I wish you were my teacher at my high school cause the one I have sucks

[Koenigsegg250]

terrible vid

[GreNadE1994]

great explanations, you'd be a chill math prof

[sweety41139]

thanks i understood it

[LLClass]

@m33lad Trigonometry is useful in the real world more so, it is used in many things eg, engineering, astronomy, architechture, surveying, ocenaography, etc etc etc.

[dianaturcios2010]

thanks u actually teach better than my teacher i wiss u were my teacher i understand u better than my teacher

[austo25]

that is the triangle

[theedman12345]

Thank you so much for thiss, I may just get my GCSE's!!!

[addalilirishtourgame]

so why was that math major here? lol

[jt302]

thank youu sooooo much , oh gosh

[13xo4life]

SOH-CAH-TOA 

[TaylerKnox]

Thank You. I mean really.

[kshitis]

thnks dude,,,,,,,,,,,

[GrayWolfPictures]

im in 7th grade and i get it...this dude is amazing!

[alaphonse331]

Thanks, love you bro.

[spoinks101]

Only if you were my math teacher......

[ill6933]

Wow, I'm with Todd on this one! Like my teacher was pree good at explaining this, but, well, I wasn't really listening (I was flirting with this cute gal). But man! You totally filled me in on what I missed all in 9 and a half minutes!!! Thank you man!! Keep up the great work!

[awaqar]

@ill6933 What would you say to this one? "Speed maths- Multiplying without multiplying". Click on my username and check the vid. Cheers.

[duiliomigliori]

THANK YOU for the time you took to do this..It's clear, concise and very helpful.

[iPwnCOD]

thanks man

[kelsimai]

thanks this helped me alot :)

[onlyEULENE]

do you know how to computer sine / cosine/tangent ... without using any calculator??

[shueke247]

Ty a lot for the video. It rly helped me out :)



[123MasterComputer]

Which App u use to write ?

[PotatoeSmiley]

soh cah toa :-)

[martystreets]

The hyp wouldn't be negative because your multiplying 7 on both sides not subtracting

[qweerrttyuiop]

shouldnt the hyp be negative cause you transposed it to the other side? or did you just multiply it both by 7? sorry im studying physics and i dont have a background in trigonometry so i dont have a clue what the hell my teacher is teaching me.

[ProtocolsMaster]

How would you find the height of a pole, me standing at the end of its shadow 10 feet away from it? I forgot how to solve that.

[TheDevilvivek]

how 7 times sin 45degree =4.015

[TheDevilvivek]

opp , adg all will be measured in degrees not in metres or centimetre

[outofmylaboratory]

@allenlistar yes.. but the point of the video is not really to show how to draw triangles to scale.

[7thAttempt]

@allenlistar Seriously get a life and stop trolling youtube! If you're studying a Major in Mathematics I would hope you have better things to do than poke holes in other peoples work. What positive contributions have you ever made to youtube / people's education ?

[Crow15mcin]

@allenlistar chill out! Its helped those who find it difficult, so go and finish your major cos your head is obviously so far up your own arse your adams apple is your the top of your head.

[0955interactive]

@allenlistar and ur here watching videos...hmmmmm

[TheAlec2012]

wow man!! I checked it and it's actually right!!

I used the formula: sin35=opp/hyp

-(then i subtituted the value of opp. and hyp.)-

0.57357643635105=4.01503505445­7/ 7

0.57357643635105=0.57357643635­105 it's correct!!thanks man!

[JiMaNeYbOb]

This was handy and made me remember alot! Thanks!!

[LordvGum]

On Friday, I will name this angle "Rebecca".

I think you teach better than my geometry teacher. Thank you so much for posting this! now I need to do other parts to prepare for my exams.

[Cam0m0]

SOH CAH TOA



[LordvGum]

@Cam0m0

xD I'm glad someone knows this.

[bigboyAllen1455]

awesome >>>>>>>>>

[trishi4u]

wow. you taught it on the best way. i wish you were my math teacher. :)

keep posting educational videos in a way where boredom cannot strike. :D

[Riot454di]

Would be nice if my teacher explained it like this...... THX :D

[aaroncarterfan911]

i really appreciate these bad boys. you have the voice of an angel.

[Missmercedes3283]

Thanks!!!!



[ams914]

Do you go to Chapman? You send like someone I took a class with.

[outofmylaboratory]

@ams914 I do not. I'm in high school right now.

[xValentinaaa]

helped me get an A on my test! 

[WeAreLegion00110]

Thats amazing

[silentcuteb0y14]

Thank you very much

[MAJESTIcag7]

YOU DOWN WITH OPP?

YEAH ....YOU KNOW ME!!!!!

[6PackJourney]

this video was viewed 3,073 times by me.

[Yawzimack]

how do i do that in my sci.calcu O.o

its casio fx901

[atamos100]

Are Hyp. Cos. and Sin. all invariables? What are they and where do they come from? (I hate just following rules or punching things into a calculator to solve maths problems without actually really understanding what I'm doing!)

[Amani13164545]

Dont you neeed to round them...you cant leave hem in point form...

[ToddHakes]

Hot damn! I actually understood this! Thanks a lot, man.

[BengBengCat]

Thank you!

[poke97]

cool i kinda get this. Although this is only the begining...

[poenedoos]

I agree with behtec15, why are you making this vid?

[NamiTokugawa]

@poenedoos why are you watching it?

[poenedoos]

@NamiTokugawa beccause I do like the rest of his videos

[biftec15]

An informative recap on some of the functions I thought I forgot from high school.

Why did you make this vid, if you don't mind me asking? Are you planning on becoming a teacher, doing it for an assignment, or do you just learn best this way?

[MasterJake777]

Great video. I know you were just demonstrating, but after you solved y, you could have just used Pythagorean theorem to solve for x. =)
