Quick Calc Question

[mayorredbeard]

Derivative of

(x)*((4+x)^1/2)

I keep getting (1/2x+[(4+x)^1/2])/[(4+x)^1/2], but thats wrong.

I dont know man. My math skills are as good as an 8th graders at best.

 

[spywarebanisher]

umm ^ means exponent?

if so then thats just x* square root of 4+x

 

[Szat]

all I take is QBA I and I think that's hard!

 

[kostonbleeds]

(4+x)^1/2 + x(1/2(4+x)^(-1/2))

say you have an equation u*v for the derivative you say div of the first times the second plus div of second times first

u'v + v'u where ' means first derivative
