I really need help on this, exam is tomorrow morning.
If F(x)=Integral from 0 to sqrt(1+x^2) of cos(t^2)dt. To what is equal its derivative? I tried this way : I put G(y)=integral from 0 to y of cos(t^2)dt. I notice that F(x)=G(sqrt(1+x^2)), so F'(x)=G'(sqrt(1+x^2)).2x/(2sqrt(1+x^2)). At final it gave me xcos(1+x^2)/sqrt(1+x^2). Is it right?
Then come the big problem. I could do this only because I knew how to derivate an integral starting from 0 to something else, but now, I have to derivate the integral from cosx to x^4 of 1/(1+z^2)dz. How to do so? Please explain each step and give me the answer.

I'm thinking the answer is 'to set the quadratic equation equal to zero.' Can anyone verify if that's correct for me?

If you add the denominator 3 to both the numerator and the denominator of the fraction 1/3 , the value of the fraction will double. Find a fraction that will triple the value when its denominator is added to its numeration and to the denominator.

"a Tums tablet (active ingredient: CaCO3) was dissolved in 25mL 0.6M HCL. It required 6 mL 0.6M NaOH to reach the titration's equivalence point."

the balanced equation for the reaction is CaCO3 + 2HCl --> CaCl2 + H2CO3

Where I'm stuck:
-Calculate the millimoles of HCl that reacted with the CaCO3

-Determine the mass (in mg) of CaCO3 in the Tums tablet


Thanks for any help!

A bag of 2000 chips is used in a game for two players, who take turns drawing 2, 3, 4, 5 or 6 chips each, but no other amount. The player to draw last loses. I can always win if i go first. How many chips do i need to draw first to guarente that i win? what is my susequent strategy?

Im not that fast with math when a math teacher gives me word problems i get all confused so if you could explain to me how i figure this out that would be great! ^.^
