Why is representing a dervitive like d/dx (x^) more better than than dy/dx, y=x^2
How does the limit work with derivatives
f′(x)=h→0limh(f(xo+h)−f(xo))
What is an equation called?
Formal Derivative
f′(x)=h→alim x−a((f(x)−f(a)))
What is this called?
When deriving an equation, its quite simple. Use the dervitive formula and plug in in values for the initial and finial value with the hypotical additional points. This than allows you to find the derivative!
True or False: The derivative formula works for lots of equations
False
Its important to analyze a limit of a derivative before making assumptions that a derivative is true.
If a limit does not exist, what does that say about the derivative?
A function f(x) is called differentiable at x=a if f′(a) exists and f(x) is called differentiable on an interval if the derivative exists for each point in that interval.
If f(x) is NOT differentiable at x=a then f(x) is continuous at x=ax=a.
True
False
f′(x)=y′=(dx)(df)=dxdy=dxd(f(x))=dxd(y)(x=a)
What does this represent.
Its important to know the definition of the derivative! It is an important definition that we should always know and keep in the back of our minds. It is just something that we’re not going to be working with all that much
True or False: The Larger the number the faster the rate of change. In terms of derivatives, the sign does not matter.
True
False
This is the next major interpretation of the derivative. The slope of the tangent line to f(x) at x=a is f′(a). The tangent line then is given by,
y=f(a)+f′(a)(x−a)
What does this equation represent?
In an Algebra class you probably only rationalized the denominator, but you can also rationalize numerators
For most values, the changing value for derivatives can be put at 0 to find the slope.
You can find the derivative of a graph by just looking at it and making estimates! Isn't that fascinating!?
The sign of the function itself is completely immaterial here and will not in any way effect the sign of the derivative
How do you find a derivative of a graph?
differentiate a sum or difference all we need to do is differentiate the individual terms and then put them back together with the appropriate signs. Note as well that this property is not limited to two functions
Example of “prime” notation
Give an example of a “fraction” notation in derivatives.
(f(x)±g(x))′=f′(x)±g′(x) OR dx(d)(f(x)±g(x))=dxdf±dxdg
What property is demonstrated here?
(cf(x))′=cf′(x) OR dxd(cf(x))=cdxdf,c is any number
What does this represent?
If f(x)=c then f′(x)=0 OR dxd(c)=0
What nickname would you give this rule in derivatives.
Iff(x)=xn then f′(x)=nx(n−1) OR dxd(xn)=nx(n−1),n is any number.
What does this represent?
(fg)′=f′g+fg′
What does this represent?
(fg)′=g2(f′g−fg′)
What does this represent?
When you see radicals you should always first convert the radical to a fractional exponent and then simplify exponents as much as possible
