    How Do You Calculate the Second Derivative of Y = f(2/x)?

    Saladsamurai i know i and wish could but yesterday i got these question and tomomorow i have got the analysis exam. I don't expect you to do my homework , but i still hope you would solve the problem i have submited. I don't know what else to say , whatever you will do with my threads i thank...

    How Do You Calculate the Second Derivative of Y = f(2/x)?

    I have problems with english ezpresions about math and i am not sure what you refer with chain rule.

    Derivative of sqrt(x^2+y^2)=2arctg(y/x)

    I know is something with derivating twice but i am not figuring anything out.

    How Do You Calculate the Second Derivative of Y = f(2/x)?

    There Fx a twice derivable function. Find Y'' if Y=f(\frac{2}{x})

    The greatest and lower value of the function in this segment.

    Thanks that's gives a clue. So i replace a and b in the function , then equals it to 0 and compare a ,b and c. Isnt it so?

    The greatest and lower value of the function in this segment.

    What is the greatest and lower value of the functiony=x+\sqrt{x} in the segment [0,4]? I knowit has to do with deriving it , but i don't know how to explain it. Any help :D

    Solve Integral: $\int\frac{x+5}{2x^2+2x+3}$

    Thanks for the answears. I haven`t got any time at all , tomorow i have the exam and i am studying some other exercises. I haven`t done much efforts on this one but i am asking you if you have got some time to solve it.I know it sounds strange but i still hope somebody with a god will would...

    Derivative of sqrt(x^2+y^2)=2arctg(y/x)

    The exercise requires the differential of the expression. I think that is dy/dx.

    Derivative of sqrt(x^2+y^2)=2arctg(y/x)

    \sqrt{x^2+y^2}=2arctg\frac{y}{x} Dont know where to start with this one either.

    Proving \frac{2}{Pi}x<sin x for 0<x<\frac{Pi}{2}

    \frac{2}{Pi}x<sin x for 0<x<\frac{Pi}{2} I dint figure out how to write Pi in symbol. I don't have any idea what to do with this one.
