Third nine weeks is about to end, this is almost it seniors (:
Now for calculus…
Linearization:
1.Identify the equation
2. Use the formula f(x)+f ' (x)dx
3. Determine your dx in the problem
4. Then determine your x in the problem
5. Plug in everything you get
6. Solve the equation
Related Rates:
1. Identify all of the variables and equations
2. Identify the things that you are looking for
3. Sketch a graph and then label that graph
4. Create and write an equation using all of the variables
5. Take the derivative of this equation with respect to time
6. Substitute everything back in
7. Solve the equation
Tangent lines?
I always think I know how to do these but never get them right so correct me if I’m wrong.
Take derivative and plug in your x and y to find the slope, then put into point slope.
Normal lines?
Same thing but negative reciprocal
Definition of a derivative?
I have noooooo idea
Integrals of trig functions?
HELPPPPPPPPPPP
Substitution?
Helpppppp more.
I know the steps I just don’t recognize them once I’m working the problem
Mean value theorem?
What is it I can’t find my notes on that…
One more thing, I know how to do average value, but I just never get the correct answer. I don’t know what my problem is, I just suck I guess.
So people should be able to get their comments in this week because I clearly need A LOT of help.
Goodnight world.

for Mean Value Theorem, the formula is f(b)-f(a)/b-a. So you plug your x and y values into the function to find the top numbers, then plug in the x and y values in the bottom; solve to find the slope. Afterwards, take the derivative of the function and set it equal to the slope and solve. Hope this helps!
ReplyDeleteMean Value Theorem is f(b) - f(a)/b - a = f'(x)
ReplyDeleteThis means you find your derivative and set it equal to the formula.
the formula is f(b) - f(a)/b - a = f'(x)
ReplyDeleteyes, you have tangent lines right! and normal lines too. it's the slope that's negative reciprocal.
ReplyDeleteobviously people already helped with MVT. haha
integrating trig functions: honestly, i didn't know this til the other day... but a lot of the time when integrating trig functions.. it uses trig identities.
like (int) sin^2(x)
^^that's an identity.
it's like 1-cos(x)/3
or something like that.. i'm not positive. go back and review trig identities. it will help
For definition of a derivative, all you do is take the derivative of what is in the parenthesis (first part)
ReplyDelete(Sinh)-(*insert terms here*)
----------------------------
#-h
Soo...you take the derivative of sinh and plug in what is given for h..usually 0! =]
