    How Do I Proceed with Variable Row Reduction?

    Can anyone help me with this. I am asked to solve the following matrix with Row Red. Algorithm, [ a 3 (1+a) | -a ] [ 1 a 3 | -2a] [ 1 1 1 | 0 ] I get to something like [ 1 1 1 | 0 ] [ 0 a-1 2 | -2a] [ 0 3-a 1 | -a] but what do I do now?

    Integral of 1/(x^1/3 + x^1/4): Can Anyone Help?

    Can anybody help me with the integral of 1/ (x^1/3 + x^1/4) (cube root and fourth root of x) I don't really know where to start. Also my roomate and i were wondering if x^sin(x) exists or if it has to be expressed and integrated as some sort of series.(something i haven't learned yet)

    Which Direction Will the Cup Slide on a Dashboard During a Turn?

    A "relative" question. Ok a coffee cup is resting on a horizontal dashboard. Part a asks at what velocity will the cup slide when you navigate a circular right turn. I did this. So, part b, in what direction relative to the dashboard will the cup slide? I presume its to the left but can someone...

    Trouble with Proof of Optimal Launch Angle

    Here is my problem, can anyone help me out? Prove the maximum range of a skier going down a ski jump is given by (theta) = 45degrees - phi/2 , where theta = optimal launch angle , phi = slope angle of take off with respect to the incline of the hill. I have the following equations to use...
