[coolflyin17]

i wish my advanced algebra teacher could teach like this

i usually have no idea what hes talking about

[rubent100]

funny how they say "not" instead of zero

[Anbaransu88]

actually u do not need to draw the graph out to find the angle..it is actually very simple equation...jz use the quadrat theory..tats simple instead of drawing the graph which is rather wasting time =.=

[fchciutare]

ur simply the best!!!!

[MrPiPPo]

i like your accent.

[B3LLEND]

Thanks. Your videos are extremely helpful you explain things very clearly. Good work.

[Barbossapasa]

Your videos are too expensive imo

[filmlinker]

This was very useful. Thank you very much. I have my C3 exam on the 15th of Jan and found this very useful!

[renegade4141]

vids are good but i hav a feeling these comments are planted

[mathstutorbiz]

why do you say that? the only comments by mathtutor will have the maths tutor user name, like this one. the only comments removed are those trying to make a link with other web sites, usually shall we say rude web sites!!

[xj4k3x]

i can see renegade4141 point its not hard to make another acount or get people you know to make good coments to promote your website

[mathstutorbiz]

True, but I don't.

[MonzLithium]

There is like 3 pages of comments. I don't think he has that much free time.

[mongomitderbongobong]

ridiculous discussion. Get a life people.

[arfanrasul]

[will070361]

attending Oxford university and still doesn't understand the difference between know and now

[thealee]

Hahaha good call

[carlalovesyou2]

how do you know when to change the mode on your calculator to radians or degrees? is it only when you are doing calculations involving sin cos or tan or not?

[mathstutorbiz]

yes, just when using trigometric ratios.

mathstutor

[Terroristbc]

What grade is this?

[mathstutorbiz]

as this is really revision of GCSE for A/AS level... plus a little... it is but an opening to the topic. very unwise to try and put grades to small snipits. mathstutor

[icemaiden02]

Thanks so much! I will be using these videos more often as they are a great help.

[hthglllkhgjg]

u need a calculator to find out sin 0.5???!

lol

[JamesCFraser]

That made me lol, too.

I also enjoyed the fact x was 30 degrees and 150 degrees.

[samioni]

well thank you..... . mathstutor

[redmfr]

This is brilliant. I studied a level maths at night school at my local college in Guildford but flunked. These tutorials are fantastic. If teaching is as exciting as this then I think I would be well on to a grade a.

These tutors are brilliant. They are marvellous.

[mathstutorbiz]

I see your point...... yes strictly speaking you are right..... when working with a function, the domain is the "object" set and the range is the set of numbers onto which the "domain maps". Unfortunately we can use words for more than one meaning. In maths, range can be used in statistics for a completely different meaning. I was using the word range just to speak of "from that value to another value". I hope my usage has not caused confusion. mathstutor

[telmanov]

I thought the range was the y values and the domain - the x values...

[mathstutorbiz]

You are very welcome. mathstutor
