Give an example of a continuous function whose derivative does not exist at x=0

Give an example of a function which is continuous at x=2 but whose derivative does not exist at x=2

Organ pipe A, with both ends open, has a fundamental frequency of 300 Hz. The third harmonic of organ pipe B, with one end open, has the same frequency as the second harmonic of pipe A. How long are (a) pipe A and (b) pipe B? You may take the velocity of sound as 340 ms-1.

i know that the answer is A.57m and B.425m, but don't know how to solve it.

I have this big, thick, woollen, black overcoat. On what occasions should i wear it? at night? my friend said it will smell if i wear it in the rain, since it's woollen. Also, should i wear a suit under it, or is it casual?

it weighs about 2kgs

I'm in Australia. Do i have to buy it online? or can i go to officeworks or other vendors and show my student ID there?

also, how much should it cost with the discount?

thanks

I'm just learning about subspaces and am confused as how to apply the 3 rules to determine if a subset is a subspace or not.

I need help with 2 questions, after that i think i should be fine.

{(x,y,z): x + y + z>=0}

and

{(x,y,z):(21x + y + 14z=0, 2x + 4y + z = 0}

thanks

Hi, i actually have a few questions about my motherboard and new ram

I was wanting to get 8gb of this ram, G.Skill [ RipjawsX ] F3-17000CL11D-8GBXL

http://www.gskill.com/products.php?index=397&c1=&c...

and was wondering if it is compatible with my AsRock P67 Pro3?

compatible memory list: http://www.asrock.com/mb/memory.asp?Model=P67%20Pr...

It's not on the list, while seemingly equivalent ram is.

The Ram is 2133Mhz, which is supported according to this page

Specs: http://www.asrock.com/mb/overview.asp?Model=P67%20...

but in brackets is "OC" does this mean i have to overclock my i7-2600k, or the ram can be overclocked from 1600 to 2133/1866mhz, or i have to use a ram cooler? what do they mean by 2133 (OC)?

If you can answer any of my questions, i would be grateful. Thanks

i have an Asrock P67 Pro3 and was wondering if this ram is compatible?

G.Skill Ripjaws X F3-12800CL9D-8GBXL DDR3 1600

I'm using an i7 2600k, with an aerocool PSU 700W

At the moment, I am waiting for my new HDD to arrive before i install cod mw2. Can I install and use cod mw2 on my current HDD, and then format the drive, then install it on my new one, with just one key? will it work or is it just for single usage?

I'd like to just play single player for now until i get a proper internet connection

Thanks, guys
