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...

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

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

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

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?

Study the curvature and the asimptotes of the function x+\frac{lnx}{x}.

Whats the fifth derivate of the function y=x lnx ? y(5)

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

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...

OK thanks a lot.

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

I have a homework about simulating the rain in C. It must require from the user the resin speed density and temperature. Can anyone help?

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

\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.

\int\frac{x+5}{2x^2+2x+3} I would be very greatfull. :D
