but what is the steps taken to solve it?

do i need (xy^2)(x+y)=6 or something?

What is the slope of the tangent to the curve y^3x + y^2x^2 = 6 at (2,1)

I'm confused what to do am I supposed to isolate y??

oh i see i messed up calculations. How exactly can you find b though?

I tried AM-GM with

and
but that had netted no real progress. I'm confused in how x+y=1 comes in to be handy

thanks for the clarifications.
I'm confused on how you found the answer to a.

g(2015) is close to g(2016)=g(672)=g(224). g(224) is close to g(225)=g(3)=g(1). So g(2015) maximum seems to be g(1)+2. So is the answer not 3?

I am a little confused on this notation and what it means? more specifically what does it mean N->N

and also what does it mean on the line with: g(n+1)-g(n)

Why did you guys remove {x}

How do u solve this?

11. Write as the sum or difference of logarithms:

{a} denotes the fractional part of a

#14 Re: Help Me ! » Sequence » 2015-03-25 09:25:45

I got (a+2e-3)^2=(a+3e+2)(a+e-4) which gives 10a+e^2+22e-4=0

Derp I thought that 3^0+1 was 1 my bad

#16 Re: Help Me ! » Telescoping sum? » 2015-03-25 09:17:34

I tried S=the thing posted and S/3, not exactly sure how to do it, I have 3^k/(3^k+1)

with r = common ratio.

So eliminate b, c and d from the GP equations and then divide the first by the second and first by the third to eliminate r and leave a pair containing just a and e.

How exactly do you "eliminate b"

#18 Re: Help Me ! » Telescoping sum? » 2015-03-25 09:08:38

Using the above, how would you get 2?

#19 Re: Help Me ! » Telescoping sum? » 2015-03-24 16:38:59

Sounds intuitive, can you try to explain what your thought process was?

#20 Re: Help Me ! » Telescoping sum? » 2015-03-24 14:32:24

o.O how in the world do you get that...

#21 Re: Help Me ! » Sequence » 2015-03-24 08:30:56

I used the method before I posted but didn't get anywhere hmm

Find the arithmetic sequence a, b, c, d if a−2, b−4, c−3, d+2 is a geometric sequence.
