Well, Sorry but I couldn't find help @ Homework section, I try out here:
Ok, they tell me to find a and b so that the function:
f(x)= *Root(2-x^2) if -root(2)<=x<=1
*x^2 + ax + b if x>1
has derivative at 1
I got that the condition for this graph to be continuous at 1 is a+b=0
And I moved...
OK.
We'll check when x>1:
lim (x->1+) of [f(x)-f(1)]/(x-1) = lim (x->1+) of [x^2+ax+b-1]/(x-1)] (from the function at my first post, I got that when x>1, f(x)=x^2+ax+b)
Ok, they tell me tofind a and b so that the function:
f(x)= *Root(2-x^2) if -root(2)<=x<=1
*x^2 + ax + b if x>1
has derivative at 1
I got that the condition for this graph to be continuous at 1 is a+b=0
And I moved to check out the derivative stuff:
When x->1+, the derivative is 0...
Hello!
The following URL shows the protein code (from Codons) but it's quite old, so I don't know if it's still correct.

That was easy, but the thing I got suck is the second problem: Triangle ABC with B=90 deg, AB=BC=a. SA is perpen to plate (ABC) @ A; SA=a.root3. M is a random point in AB. E is the midpoint of SC. Let MB=x.
I 'm done with the first request: Prove that a plate alpha consists of ME and is perpen...
Hello! see if you can get the results same as me ):
Triangle ABC with AB=AC=a, BAC=90 deg. SA is perpendicular to plate (ABC) @ A. SA=a, also! In SB: ES=2EB. H is in plate (SBC) so that AH is perpendicular to plate (SBC). Plate alpha consists of AE and perpendicular ro plate SBC. Figure out...
They are continuous in '1'
When you check out [f(x)-f(1)]/(x-1), will we need to let them into ways: x->1+ and x->1-, right?
But how to write down? :-)
Andm you see, you need to download the img file, any better way so that it's shown in the post? As some mathematical functions are long and...
Can I upload the images here? so that whenever you choose my topic, they're shown, no need for you to open attachments?
Any way, I am a non-native so I get difficulties solving this problem. Tell me! (it's easy but I can't use English to state some sentence)
The URL of the problem:
