How can i do these problems?

Postby jpd75 » Sat Jan 16, 2010 8:27 pm

Can anyone tell me how to workout this problems, with the answers? I'd really appreciate it.



#3) Find the derivative of the function
y = 6 / x^2 - 3 / x

dy / dx = ?

#4) Find derivative of function
y = -9 / [2nd root SQRT(x)]

#6) Find the slope and equation of the tangent line at the given x value:
f(x) = x^4 - 2x^2 + 1 where x = -2



If you could please work these out I would really appreciate it. Thanks all!
