1. 8sqrt(x^4-4x^2)

MATH]8*(x^4-4x^2)^(1/2)[[/tex]....exponentially sqrt=x^(1/2)

Outer function is y= 8u^(1/2)

Inner function is u=x^4- 4x^2

rememberthe chain rule is dy/dx= dy/du * du/dx

Derivativeof y= 8u^(1/2) ..... power rule

Now,

*

Then simplify,

2. Use parenthesis to say what the equation is.

Is it (csc^2x)^2 or perhaps (csc)^2x^2 ?
