Nah. Initially awkward and uncomfortable, but ultimately all good.

She's probably gonna flame me like my other teachers. This is NOT good.All I know is that I will feel very salty.

If y= asinct + bcosct where a, b, and c are constants, then what is the second derivative of that?I'm stuck where y'' is [ac^2(-sinct)] - [bc^2(-cosct)]I may be wrong in my execution because it's not any one of the multiple choice answers.

what are the multiple choice answers? Maybe you should help me!

If y= asinct + bcosct where a, b, and c are constants, then what is the second derivative of that?

ac^2(sint+cost)

How did you get that?

You mean the work? My dad's friend(software engineer) did it for me. I'm more of a physics gal. Sorry Was it the right answer?

So Rach,How did the meetings with your teacher go? Were you right or wrong about what you expected? Was she as scary as you thought? Did you actually received help?

Umm... so you're teacher did have reasons to be concerned but was wrong about what was wrong. You clearly need glasses!(or a magnifying glass.)

First she tore me apart.Then we went over the review worksheet I did...I GOT EVERYTHING RIGHT!She felt soooooooooooooooooooooo salty!!! But then she decided to tear me apart more. She thinks that I'm trying to fail her class. We then went over another test that I failed, and it turns out I wrote down the right answers for like five problems but circled the wrong ones.

Well there were a couple problems where I did stupid algebra mistakes. Like I remember I added 5x-7x and got 13x.And I already wear glasses.

Dude the hardest part of calculus is the algebra. Seriously. Stupid mistakes will screw you up so bad.

What's the derivative of sin^2(x)?Note: it's not sin(x)^2 It's sin^2(x)Would you just do power and chain rule? So would it be [2sin(x)][cos(x)]?EDIT:I also need the derivative of sin(X)^2and the derivative of ln^4(15x)and the derivative of log5(x-7)I have a test tomorrow and that's what I'm unclear about. When you have ln raised to something and when you have log of something.

my essay question was on the Free Will theodicy. So fun!

My English teacher is terrorizing me. He keeps giving me low scores because he doesn't understand what I write about. I want to kick him in the b***s.

I had an economics teacher give me a low grade on a test because I "used techniques we hadn't learned in class". I didn't realize my grade should go down for being ahead of the class. I'll dumb my answers down next time...

When a circular plate of metal is heated in an oven, it's radius increases at the rate of 0.01 cm/sec. At what rate is the plate's area increasing when the radius is 50cm?

The radius r and area A of a circle re related by the equation A = pi(r)^2. Write an equation that related dA/dt to dr/dt.Apparently the answer is dA/dt = 2pi(r)[dr/dt]I think I kinda get the logic, but could someone go through the work for that?EDIT:I actually know the logic, but I don't know WHY.

A=pi(r^2)differentiate both sides with respect to time (treat A and r as a function of time maybe? not sure )dA/dt=pi(2)(r)(dr/dt)dA/dt=2pi(r)(dr/dt)

What the heck is...the dirivative of...(the inverse of sinx) - (the square root of 1-x^2)I got (1-x)/(the square root of 1-x^2) but that's not one of the answer choices.

It might just be an expansion of that.

(sqrt(1-x^2))/(1+x)?

I am the biggest idiot...

I'm doing geometry right now, and it's eassyyyyyy.

Wait till you get to calc...

I'm planning to take calculus AP junior year (high school)!

Is that AB or BC

Isn't calc 3 an AP course too?There's only like 10 kids taking that class in my school and I heard they talk about the philosophy of math.
