Post your questions about your homework here! I got an easy one to start. Someone explain an inscribed angle to me and the relationship between an inscribed angle and the central angle please :)

I guess we could do that thing where we hire special tutors for the individual subjects! So post in here which subject you specialize in and I can put you down in the OP as a tutor!

One is inscribed, the other is central. Their relationship is "it's complicated".

You're welcome.

It also helps when you ask questions, to post the subject it is referring to, as certain terms may mean different things in different sciences.

Good idea, that might help

FTR, my question was about Math (Circle Geometry)

Steven Stamkos way to post LMGTFY.....I would not have started a thread if I already googled.....

A central angle is where the "corner" of the angle is at the centre of a circle, so that each arm of the angle is a radius of the circle

an inscribed angle (subtended by the same arc) would have the same two endpoints but the corner is also on the cirlce.

this inscribed angle would be exactly half the size of the central angle

Is the DELF exam the French one? Because I'm pretty sure that it was taken out of high school at least. I haven't taken any university French so I can't help you there.

Haha I will actually help if I have time, and if i understand it. I should know pre-university math, a bit of calculus, and first year uni bio and chem material.

I'm currently in first year pre-med bachelor of science (4.0 GPA :frantic: )

I was thinking of taking French in university as I have taken it all the way through high school. Do you recommend being able to speak and write it fairly fluently because I understand French fairly well, I just can't form full paragraphs very well.

Well I'm in grade 12 and I've taken french all throughout high school too
I guess if u r going to take it in university than yes you should be able to speak,read and write fairly fluently... although i'm not sure exactly what the skill level should be for university

If u r in grade 12 than u should be atleast at A2 level on the DELF exam

This is what is expeted at an A2 level

I'll help out in general. I'm fairly good at math and most sciences and I can hold my own in everything else. Im not too good at English though. I'm currently in my first year at Kwantlen taking courses that interest me because I'm not sure what I want to do with my life just yet.

y= mx^2 + b

m is your slope. larger M value = narrower parabola,

If your equation is just x^2 + b, it will be easier.

B is your y-intercept and your minimum (or maximum if your slope is negative) value.

To graph it without a calculator, I'd suggest making a table of values (plug in for x to determine y) and graphing it that way. It is the simplest way without using calculus.

to add to this:

factor as y=a(x-h)2 +k (by completing the square)

then the point (h,k) is where the vertex is located, and as stamkos said a is how fast the parabola opens up

Ahhh...just in time for finals.

Trigonometry/Calculus (First Year):

Consider a new function y=cosx and 0<x<pi (less than or equal to). What does cos^-1(-1/2) equal to?

I know this has something to do with the quadrant stuff from grade 12 but I can't seem to remember it,

x between zero and pi means that you are looking in the first or second quadrant (anything above the x-axis). the number -1/2 that you are taking the arccos of means that you are looking at a 1-2-sqrt(3) triangle (remember special triangles). that should be enough haha, but if it isn't post again and I can give you more hints

This question is killing me, A rock is released from the top of a 30 m-high cliff at the same time as a ball is thrown upwards from the base of the cliff at 20 m/s. How much time elapses before they collide?

You can actually ignore gravity here, as it has the same effect on both objects. the relative velocity between the rock and the ball is constant, and the distance they need to cover is given
