This week in math class with learned about the chain rules and finding dy/dx. not only that but finding dy/dx' as well. for EXAMPLE finding y'' of y= cot(x). well, y'=-csc^2(x). so y''=-2cscx(-cscx)(cotx) which equals -2csc^2(x)(Cot)x. it's pretty simple, Finding the second derivative IMPLICITLY is something else we learned about.
