Definition of a Limit
|
if all values of f(x) are close to L for values of x that are sufficiently close, but not equal, to a. The limit L must be a unique real number.
|
|
Newton's Second Law
|
Second law: The acceleration a of a body is parallel and directly proportional to the net force F and inversely proportional to the mass m, i.e., F = ma.
|
|
Newton's First Law
|
The velocity of a body remains constant unless the body is acted upon by an external force.
|
|
Newton's Third Law
|
The mutual forces of action and reaction between two bodies are equal, opposite and collinear.
|
|
Pythagorean theorem
|
a^2 + b^2 = c^2 (only works with right triangles)
|
|
Rule One for conversions
|
Always Multiply by one!
|
|
Limit Theorem
|
As x approaches a, the limit of f(x) is L if the limit from the left exists and the limit from the right exists and both limits are L.
