Oh I see. Thank you.
Hold on, why are you using sin and tan?
I'm sorry, but you've lost me. We've not done this type of thing in school yet.
I would of rounded and got 7 anyway. But the whole double root thing is just over my head. I don't think we need to know that at moment. I dunno lol. But at least I know how to read the exact value triangles now. :3
Ahh, I see. Post away.
Thanks, that really helped. I'll practice using that equation over the weekend.
I don't think we've done roots. What do they look like? sin^2 = ? or something?
Ahh! So the answer would be;
h(x) = f(g(x))
h(x) = 4x - 18
I see, I thought it would be a little different with a third letter involved.
What is the difference between calling something x or y?
So what happens when it's like h(x) = f(g(x)) ?
I saw something like that. What's the difference?
Nothing. But there was a third one involved too so that one confused me in class.
Have you sorted the trig question because I can give you exactly the diagrams you need.?
I'll take all the help I can get. Fire away.
Oh, nevermind. Thanks.
So what happens when It's like h(x) = f(g(x)) ?
I saw something like that. What's the difference?
Not sure how it's 4x - 18. Like, I can't see the jump? You know what I mean?
AHH. Oh get it now. Much appreciated, a-thank you. :L
One topic down.
I need help with the ... uhh... I dunno what it's called. But it's like;
g(x) = 1x - 5
f(x) = 4x + 2
And then you've to do f(g(x)).
My problem is subbing it in. My teacher teaches at a fast pace so I've not had time to absort what I have to do so I'm sorry if my descriptions of math are all higglety pigglety.
I know you've to sub it into an equation where there is an "x" but I don't know how to start.
Oh. Thanks.
How do I read the triangles though?
I don't really have a question. ^ It's more understanding of what I'm doing in class. I just need help on how to read the triangles from the picture.
Hi
I think your diagram is wrong, you can't have a right-angled triangle of sides 1, 2 and √3, like that since
I think that the hypotenuse should be 2 and the side which is currently 2 should be √3.
The teacher said that diagram was to help us find the angles, I don't really know how to find the answers and stuff.
I think I may have explained myself wrong... uhh... the triangles are related to sin graphs. Like to find the points of degrees. Does that make sense? There's radians involved too.
I got told that Pi = 180 when doing this. Like, if;
(0≤x≤2(Pi)) = (0≤x≤360°)
It's optional to work in either degrees or radians, but I prefer degrees.
Oh, idk how to fix it. FAAAAIIILL. I rotated the image but it didn't seem to work.

No idea how √3 = 60° or any of it, really.
(Also no idea how to use the syntax by the way, but bare with me. xD)
Lol, the lighting in my room isn't that good. xD
Forgotten how to do this lol. It's not a manga pic btw it's just what I saved it under for some reason. :3
Uhh, if you don't mind I would like to go over notes I have received from my maths teacher here. I don't quite understand the way she has put them and I sort of need help with my higher maths, so I'll be putting up stuff here almost daily and would appreciate if you could help me with them. :3
Please note that I am a visual learner and don't really benefit from exercises like, learning games and stuff.
'Kay, first up is exact values. I don't really know on how to find the angle? I know it has to do with Basic trig, graphs and the use of the CAST diagram... I think I'm getting confused with finding points on a graph, but anyway, I know there's the triangle involved (I don't know how to read it) and the table, but that's about it.
Any tips? I know this is a must to learn, so that's why I'm starting with it.
The rules are simple; just ask the person below what colour their ____ is while answering the persons question above you. :L
What colour is your shirt?

Oh, that site died. xDD I have a new one, 13 members!
I have Animal Crossing for the DS! I haven't been on it in months. I finished playing after I got all the fish and bugs (hated the tarantula ) and I'm just missing some of the Gyroids. I mean to get it for the Wii.
Me too! The Wii is much better than the DS, I hate the scorpian and tarantula they chase you. O_o
If you get it for the Wii I could tell you what happens if you befriend Brewster. xDD
