1) find the derivative of both sides of the function
2) put all terms with a y prime on the same side (y prime aka derivative of y)
3) factor out a y prime
4) solve for y prime

What is the Chain Rule? When can it be used?
Front
deriv of [f(g(x))]= deriv of f of g(x)*deriv of g(x)
It can be used anytime
Back
What is the Alternate Difference Quotient Equation and what does it find?
Front
limit of (f(x)-f(c))/(x-c) as x-->c
It is finding the slope of the tangent line at a particular x-value
Back
what is the Difference Quotient Equation(a.k.a the limit definition of a derivative) and what does it find?
Front
f'(x) = limit of (f(x+changex)-f(x))/(changex) as the
changex-->0
It is finding the slope of the tangent line everywhere

Deriv of f(x)=tanx is?
Front
sec^2x
Back
What is the quotient rule?
Front
h(x)=(f(x))/(g(x))
derivative of h(x)=[g(x)deriv of f(x)]-[f(x)deriv of g(x)]/(g(x))^2
Back
Deriv of f(x)=cotx is?

Deriv of f(x)=cosx is?
Front
-sinx
Back
Deriv of f(x)=secx is?
Front
tanxsecx
Back
What is the product rule?
Front
h(x)=f(x)*g(x)
derivative of h(x)=[f(x)deriv of g(x)]+[g(x)deriv of f(x)]
Back
implicit differentiation
Front
not clear; when you can solve for y as a function of x
EX) y^3+y^2-5y-x^2=4
Back
derivative
Front
slope of the tangent line
Back
When do derivatives not exist?
Front
1)At a "spot" of discontinuity (pt.(hole), infinite(VA), jump)
2)At a cusp(sharp pt.)
3)At a vertical tangent line
Back
explicit differentiation
Front
very clear; the variable y is explicitly written as a function of x and it only works when you can solve for the function explicitly
EX) y=3x^2-5
