1. ## Biology Extended Essay

I don't think you'd be able to get much out of the first one and in regards to the 2nd one, I'm not accusing you or anything, but I've seen that EXACT extended essay topic online done by some one else. You'll probably get in trouble for plagiarism if you go with the second
2. ## SL Chemistry Paper 2

I think the third mark is just saying that particles must collide
3. ## SL Chemistry Paper 1

What was the answer to the one with Si bond shapes?
4. ## SL Chemistry Exam Dilemma!

It's definitely not easier than standard provincial-curriculum level chemistry. At my school advanced chemistry is a prerequisite for IB Chemistry SL.
5. ## Trigonometric equations in quadratic form

For the first one use the double angle identity to make sin(-4x)= -2sin2x cos2x step 2: move -sin2x over: -2sin2x cos2x - sin2x = 0 step 3: factor: sin2x ( -2cosx - 1) = 0 step 4: set both factors equal to zero: sin2x = 0, x=0 2cosx - 1 = 0 cosx = 1/2 x = arccos(1/2) x1 = 1.05 step 5. x2 = pi - 1.05 = 2.09 step 6: add 2pi to 1.05 and 2.09 till you have all the values within the restriction! ( i might do the others when im less tired!)
6. ## Help! Math IA survey about music

1) Male 2) Yes 3) Guitar (not well)
7. ## [URGENT] Chemistry IA

Each section needs two different labs

.
9. ## New angle measurement?

Yeah you're completely right! I know it would be useless to actually use. I was just wondering if it would work and why the creator of radians used radius instead of diameter to measure angles
10. ## New angle measurement?

Yeah I didn't think about that. But would it really make it harder to work with though? for example 30 degrees would just be Ï€/24 diametrans. Not better or worse just different. I guess trigonometric functions would be weirder too cause cos(0 would be 1/2 diametrans. And the amplitude of sin and cos graphs would be 1/2
11. ## New angle measurement?

Its basically the same as radians except times two. I just wonder why the person who created radians used radius rather than diameter.
12. ## New angle measurement?

Ok so I was thinking about radians and then I thought why is radians in terms of a radius?. Why not use the diameter to derive an angle measurement? I'll call it diametrans for now. so since one full turn is equal to 2pi radians, it would be Pi "diametrans" and half a turn would be Ï€/2 diametrans and so on. I guess its not groundbreaking or anything but did I think of a viable new angle unit or has it already been made but I don't know of it? Or does it not make sense?
13. ## What is the difference between HL, SL, Studies? Which to take?

IB math is kinda like all other IB courses. SL goes over the same topics, but HL goes more in depth and has Options. Math Studies barely touches the same topics as the others and is more focused on the application, while the other two are focused on math by itself.
14. ## Why don't you believe in God?

I just can't see how a world as complex as ours could have happened just because. I feel like it's not absurd to believe in an intelligent design
15. ## Why don't you believe in God?

Christianity is just as close to being the "default" as atheism. A baby doesn't "believe" anything, so it can't believe there's no God
