Hi everyone; I hope I'm doing this right LOL. So, it's Principles of Math 11, and I just can't do it (trust me, I've tried). I'm working with Quadratic Functions and that sort of stuff...(also let me add that I can't do math to save my life). I'm the sort of person who needs examples. However, as so...

Thank you so much!!!

Hi everyone, I hope I have this in the right section. So, obviously, I've got this problem and I just can't figure it out. (I swear to God I'm a retard when it comes to math; have been since like, 8th grade.) Given circle with centre O with DE tangent at B. Find the measure of x. http://i73.photobuc...

*gasp* Yes@@ Thank you so much!

Hey everyone, I hope this is in the right spot...For some odd reason this was never covered in my book so I'm not quite sure what to do with it. (that happens quite a lot actually... :shock: ) Given the diagram below, find the horizontal distance AB. http://i73.photobucket.com/albums/i206/Nienna_pho...

Hi everyone, I couldn't tell where to put this, so I thought here would be best, I hope that's ok. Anyways, I don't really have a question like all the others, more just topic based. How On Earth Do I Do Math Transformations?!?!? My book is useless! It gives me a load of diagrams and numbers, and ex...

f(x) + a is f(x) shifted upward a units f(x) – a is f(x) shifted downward a units f(x + a) is f(x) shifted left a units f(x – a) is f(x) shifted right a units –f(x) is f(x) flipped upside down ("reflected about the x-axis") f(–x) is the mirror of f(x) ("reflected about the y-axis&quo...

Thank you sooo much! You've been such a big help, and I can get by this topic now ^_^ Thanks again! *hugs*

If someone could point me in the right direction of where to go with these sorts of problems, I would be so greatful :p

Solve the equation for x, where 0</x<2pi

2 sin x + 1 = 0

I'm sorry, I know this is probably a problem I should be able to do in my head or something, but I'm still confused :(
