*handshake* I'm not really into hugs.

Now it works.

Extension Mathematics: 81% 1st. PDHPE: 94% 1st. Chemistry: 69% 2nd.

I got Captain. :)

No preference.

:uhhuh: Me too.

A lot.

State the domain and range of the function: y = 2 root (25-x2) <SUP><SUB></SUP></SUB>

But I do music 1.

Create a poll so you can see percentages of who thinks modern and who thinks ancient.

Horror fiction is, broadly, fiction in any medium intended to scare, unsettle, or horrify the audience. Historically, the cause of the "horror" experience has often been the intrusion of an evil—or, occasionally, misunderstood—supernatural element into everyday human experience. Since the 1960s...

Music has the lowest scaling of all. :(

Chemistry's winning. :)

Factorise a3 + b3. Hence or otherwise, show that (2sin3A + 2cos3A) / (sinA + cosA) = 2 - sin2A, if sinA + cosA < 0 and sinA + cosA > 0

An easy one: Find all real numbers x which satisfy the equation 4x4 = 4x2 + 3

So is it just sec2x?

How many different arrangements of just five of these (the seven) marbles are possible?

I haven't done differentiation of trigonometric functions yet. You're correct by the way.

There are three identical blue marbles and four identical yellow marbles arranged in a row. How many different arrangements are possible if... - There are no restrictions? - Just five marbles are used?

Next question: Simplify: tan2A(1 - sin2A) Hence solve: 4tan2A(1 - sin2A) = 1 for 0o < A < 360o
