    Understanding Division by Zero: Exploring Logical Reasoning

    I think one of the main problems with this statement is that it does not make sense to divide something among zero people while looking for the amount each person received. If you have a cake and nobody wants it, then yes the cake is still there, but this is not the same as dividing the cake...

    Area of a right-angled triangle

    like the triangle is sitting on the hypotonuse? is this a 45-45-90 triangle or can we not make that assumption?

    Can someone tell me the essence of derivative?

    another hint see what from: (pi(r+e)^2+pi*r^2)/h you can factor out front and you will learn one of the fundamental problem solving techniques of derivatives.

    Integrate cos^3xdx - First Clue: Substitute (1-(Sinx)^2)cosxdx

    thanks for the help. This trig integration stuff is killer OK the reason I asked was because I have a lab assignment where I have to calculate the powers of \int cos^n[x]dx where n is odd numbers from 3-13. So can someone please look over my work for \int cos^5[x]dx and make sure it looks...

    Integrate cos^3xdx - First Clue: Substitute (1-(Sinx)^2)cosxdx

    Any suggestions on how to integrate \int cos^3xdx My first clue would be to substitute (1-(Sinx)^2)cosxdx but any clue to go after this?

    Help can someone differentiate e^(nx)

    It's mightily unnecessary as one term will automatically go to zero, and yes I missed his algebraic mistake

    Help can someone differentiate e^(nx)

    Hmm . .. I don't think that is quite legal since e^n is a constant, the product rule only applies if you have two functions. you could alternately take the log of both sides which may look something like: lny(x)=lne^nx differentiate with respect to x y'/y=n y'=ny and since y= e^nx...

    Exploring Mathematics without a Calculator: A New Endeavor

    The trick is really to just find sin, then use relationships to figure out the other 2.

    Are mathematics' unsolvable problems caused by its foundations?

    Well 0 is valuable for equations especially for describing systems of forces in equilibrium. Or Calculating extremum. Or place holding I agree a lot of funky stuff does happen around 0 but that is no reason to get rid of it.
