Find the derivative
U(x)=[(x^23)(3x^3+1)]/(x^41)
Prove for 2 twice differentiable functions f and g
(fg)''=f''g+2f'g+fg''
U(x)=[(x^23)(3x^3+1)]/(x^41)
Prove for 2 twice differentiable functions f and g
(fg)''=f''g+2f'g+fg''

That's the LOGICAL answer. Wow, what are these 'numbers'

its B and D since Y1(t) has a greater amplitude than Y2(t). The way that question is worded is kinda annoying lol

I don't know what you know so far so no, probably not. What pure posted was trigonometry. Have you taken algebra?@Dapocalypse wrote:Do you guys think you can explain calculus to me.

ok, thats like nothing, I couldn't even teach you the basics of calculus.. or even trigonometry.. lol@Dapocalypse wrote:I have basic algebra knowledge
Most advanced thing I know
(2x+5)+(6x18)=3x+5
8x13=3x+5
8x=3x+18
5x=18
x=3.6

thanks pure. Too bad I'm a rightminded mathhater who can't do 9+11 without concentration
