Homework Statement f(x)=X^2/(x^2-16) f(x)=1+x/1-X f(x)=X^3(X-2)^2 Ive done the first and second derivatives but they just don't seem right Homework Equations Quotient/Chain/Product Rule The Attempt at a Solution f(x)=X^2/(x^2-16) (X^2-16)(2X)-(X^2)(2X)/(X^2-16)^2...

Am I doing these correctly?

Well here's what I've got, I think they're right but I'm not sure. f(x)=X^2/(x^2-16) (X^2-16)(2X)-(X^2)(2X)/(X^2-16)^2 f'(x)=-32X^2/(X^2-16)^2 (X^4-32X^2+256)(-64X)-(-32X^2)(4X^3-64X)/(X^4-32X^2+256)^2 -64x^5+2048X^3-16384X+128X^5-2048X^3 f''(x)=64X^5-16384X/(X^4-32X^2+256)^2...

I'm mostly having trouble with the second derivatives.

f(x) = x^2 and g(x) = x^-2 x^2/x^-2 ((x^-2)(2x)-(-2x)(x^2))/ (x^2)^2

(g(x)*f'(x)-f(x)*g'(x))/g(x)^2

Homework Statement Just trying to find the first and second derivatives. X^2/(X^2-16) 1+X/1-X X^3(X-2)^2 Homework Equations Quotient Rule/Power Rule/Chain Rule The Attempt at a Solution

So how would I set up the equations?

What moment? Moment of inertia?

Homework Statement A .110-kg remote control 21.0cm long rests on a table, with a length L overhanging its edge. To operate the power button on this remote requires a force of .365N. How far can the remote control extend beyond the edge of the table and still not tip over when you press the...
