    Number Theory Suggestions for Analytic Number Theory textbooks

    Something other than Apostol's book which I find lacking in motivation. Not too advanced, since it is my first encounter with ANT.

    Central limit theorem and estimates of probability

    It's not 1/2. Check your calculation.

    Central limit theorem and estimates of probability

    As Simon said you are using p for two different things. You can use the fact that p(1-p) (where 0<p<1) has a maximum value(find it). You can use it to get a bound for your answer.

    Calculating Tension in Friction & Pulley: Solving for a=3 m/s^2

    Write the Newton's laws in the frame of the ground. It is an inertial frame. Write down all the forces(along both axes). Also observe that for every meter the car moves, block A moves by 2 meter.

    Maximize Value: Solving for Largest Possible Value Using Factoring Method

    yes,x=y is only possible. By graphing all lines and checking possible values for x, i get x between -20 and 20. And maximum is indeed for x=-20.

    Maximize Value: Solving for Largest Possible Value Using Factoring Method

    That is not going to work.What you say is maximum is true only for a=b,if you apply AM GM inequality on a,b.Doing so for 1st 2 expressions give x=140,y=260. *I don't know the answer*

    How Do You Calculate Kp and Qp for Chemical Reactions at Equilibrium?

    no you don't have to include no.of moles of solid. no, it would go backwards,as Qp>Kp. for (iii) and (iv) read le chatelier's principle. http://www.chemguide.co.uk/physical/equilibria/lechatelier.html#top

    Is the Square Root Function Bijective in all Branches of Mathematics?

    to prove square root function to be bijective you need to specify the domain and codomain of the function. if codomain is set of real numbers, then its not bijective.

    Chemical Kinetics - Activation Energy and gr

    the integrated rate law for 0th,1st,2nd order might help for problem 13. for q.14 use first two data to find the rate law and rate constant. then using arrhenious equation and the third data find rate constant at 650K. use the integrated form of rate law to find the required time.

    A question on impulsive tensions

    i get 0.782 if i take g=9.8 m/s^2.

    Resolving Multiloop Circuit Configurations with Delta Star Transformation

    if you need equivalent resistance, then it can be reduced to series/parallel combination by first using delta star transformation.
