Chapter 3 Flashcards
What is the constant rule? (DxC=?)
The derivative of a constant is always 0. (DxC=0)
What is the derivative of x? (DxX=?)
The derivative of x is 1. (DxX=1) (y=x)
What is the power rule for derivatives? (DxX^n=?)
The derivative of x^n is nx^(n-1). (DxX^n=nX^(n-1))
What is the sum/difference rule? ((f+g)prime=?)
The sum/difference of (f +/- g)prime is fprime +/-g prime.
What is the derivative of a constant times a function of x? (DxCf(x)=?)
The constant times the derivative of the function of x. (DxCf(x)=C*fprime(x))
What is the definition of the number e?
The number e is such that the lim h->0 (e^h-1)/h=1. (That the tangent slope of e^x at x=0 is 1)
What is the product rule? ((fgl*m)prime)=?
((fglm)prime= fprimeglm+fgprimelm+fglprimem+fgl*mprime
What is the quotient rule? (f/g)prime=?
(f/g)prime=(fprimeg-fgprime)/g^2

What is lim (theta)->0 Sin(theta)/(theta)?
lim (theta)->0 Sin(theta)/(theta)=1
What is lim (theta)->0 (Cos(theta)-1)/(theta)?
lim (theta)->0 (Cos(theta)-1)/(theta)=0
What is the Chain Rule? Dx(f o g)(x)=?
The Chain Rule states that the derivative of (f o g)(x) is f(prime)(g(x))(gprime(x) (the derivative of the outside function with the inside function intact and still inside it multiplied by the derivative of the inside)
