For the other one...
Suppose that log_3 5 = p/q p,q relatively prime
5=3^(p/q)
5^q=3^p, which is impossible if p and q are relatively prime (5^q ends with 5 or 0 and 3^p ends with 3, 9, 7, 1 or 3)
Re: Quick thread -How much derivation in Parametric Equations of Parabola is required
I don't mind 3U parametrics. All the questions are pretty much the same. But I hate the 4U conics questions involving lengths of algebra. I can still do it but it's not my favourite topic. Thankfully it's...
Re: Quick thread -How much derivation in Parametric Equations of Parabola is required
Because it's logical and interesting. And plus all the questions are pretty much the same.
Series applications (Loan repayments etc) is also one of my favourites in the HSC course. Too bad it's hardly ever...
Re: Quick thread -How much derivation in Parametric Equations of Parabola is required
If you knew the nature of the 3U exam then you'd know that they wouldn't put that in.
Re: Quick thread -How much derivation in Parametric Equations of Parabola is required
Probability happens to be my favourite topic. So naturally I would give you a tough one.
But I don't see a proof of the wallis product?
Re: Quick thread -How much derivation in Parametric Equations of Parabola is required
And you can't seem to accept the fact that 4U students can find the equation of a curve and that Parametrics is basically a watered down version of conics. Note that the parabola is a conic with eccentricity...
Re: Quick thread -How much derivation in Parametric Equations of Parabola is required
Yeah except for the fact that you do similiar or harder variations of parametrics in conics, a 4U topic. So it's a topic that 4U students would probably be advantaged at if anything... Smart one dumbo
Re: Quick thread -How much derivation in Parametric Equations of Parabola is required
You honestly don't think 4U students would know how to derive the equation of a tangent? LOL
