  1. Hey Guys,

    Lately I have been trying to self teach myself Objective C and trying to dig up and collect resources. I have collected a bunch of books and some videos from Lynda.com. Hopefully you guys might know a lot about Objective C and help me out here. So, I was wandering a good reference to help me learn this.

  2. I know there are as many Atheists here as Theists in this forum. Anyway I'm here to ask what's your favourite Atheism Book?

    mine - "The God Delusion" by Richard Dawkins and "A Manuel for Creating Atheists" by Peter Boghossian

  3. Hello Guys,

    I've been away for a while for some reason. It's good to be back. Anyway, Chikis I understand from your question that you just have to find the inner most angles and the remaining side of the triangle formed by point P,Q and R using the Trigonometric Laws( Cosine and Sine Laws as your wish). I hope you know them. Studiot explained you very briefly what bearing is. You just have to interpret the angles you find to bearings.

  4. You could also solve considering that the two quadratics have come root -1 since there is a hole at x= -1 and as given x-4 (because x= -4 is a vertical asymptote) is also the root of the quadratic which is denominator. Now we have 3 of 4 linear functions needed 2 for the denominator and 1 for the numinator with one left. We could find this using the two givens the intercept and the limit by assigning the expression aX + b..... then evaluate the what has been asked..

     

    the function (aX + b)( X+1)/( X+1)(X-4)

  5. You are given F(v) = -Cv2, the force as a function of velocity, and you need to show that x - x0 = (m/C) ln(v0/v) where m = mass and C is some constant.28gtcol.gifMy question is why and how does definite integration work when you have 2 variables?339k4lh.gifI mean I was able to finish the problem using this as I've seen it be used in the textbook itself and also some math books, but I don't really understand or know how it works. In calculus classes, and also my book, definite integration is done using 1 variable. I mean we do multiple definite integrations but that's only 'on one side' and 'one at a time' and I've never really been taught definite integration on different variables on 'both sides' of the equation.I feel like because the right side is being evaluated from 0 to t, the other side should be evaluated from 0 to t also.

    I think the case is solving the deferential equation:

    F(v)=MVdV/dx = CV^2

  6. Actually finding the domain of a function is pretty easy. You don't have to calculate the derivative of the functions just only smart moves.

    First logarithmic function only works for positive values except the domain is complex numbers. So this is more than enough for your question.

  7. Hi guys,

    To day I don't want to talk about issues or problems but about a mobile app for science forums. I'm not a programmer or some thing like creating apps but I think there are so many best guys to do this.

    So, Why aren't you guys create android or iOS app for science forums like physics forums. It would be cool for us to surf around.

  8. John Cuthber are you challenging me. I was only pointing out my idea. you could agree or disagree on the point.

    So, what do you think?

  9. I don't think there is no enough info. If the acid reacts with the base completely then there moles must be equal.

    Which is .068*27.42== the mole of the acid ,then you can proceed.

  10.  

    I do not understand where to start since to find number of moles of NaOH you need the volume but the volume was not given.

    Have you read the question carefully, it ask you to find the volume? Let me give you a little push use V as the volume and do all the calculation.

    Show us a little work of yours so that we can help you!

  11. Looks like, it is very good question. Any way to clarify and give you a hint try this simple vector formula.

    Vpa = Vpg + Vga

    Vpa is velocity of the plane relative to the air.

    Vpg is velocity of the plane relative to the ground.

    Vga is velocity of the ground relative the air.

    Try to change all the velocities to Vectors assuming the ground as an origin. I bet you know very well about Vectors. Good Luck.
