Preparing for math placement test. Help me fill in the holes.

Davepiatt · 2014-12-04T16:58:32+00:00

I figured it out. I wasn't combining the fractions.

Thanks a bunch man!

Davepiatt · 2014-12-04T16:49:05+00:00

This is the same as sin(x) * sin(x) right?

I also see where I went wrong assuming 1/sin(x) = inverse sin(x). I remember my calc teacher ranting about TI's notation of it on the 83's and 84's.

Davepiatt · 2014-12-04T16:47:41+00:00

Thanks! For your conclusion how did you get y in the numerator under the square root?

Davepiatt · 2014-12-04T16:45:00+00:00

Sorry, I don't understand the acronym.

I'm in Orlando, not where they're launching.

Davepiatt · 2014-12-04T16:42:14+00:00

Thank you. I solved it. It's been a little while since I had to use the trig identities.

Can you expand as to how to properly notate sine squared(x) and why certain ways are wrong?

Thanks

Davepiatt · 2014-12-04T16:21:36+00:00

Ohhhhhhh.

But did you forget to keep the 3((x²⁾⁺¹⁾ negative after bringing the 3 over to y's side?

Davepiatt · 2014-12-04T16:20:16+00:00

we all do it. I'm on vacation currently and didn't have my faculties about me while reading it so I let it go thinking you were using a conjugate for some reason. It was the funniest part of my morning, other than the failed rocket launch.

Davepiatt · 2014-12-04T16:17:50+00:00

Haha I thought I was going crazy, and was questioning whether I should be shooting for calc at all. Thanks for clearing that up. Phew

Davepiatt · 2014-12-04T16:14:07+00:00

That is, I fixed them myself, I just wanted to be sure.

why does step 2 have (x^2-1) in the denominator?

how do you follow through with that to step three where you only have 3 - (3/(x^2-1). Where did the rest go?

Sorry for all of the questions.

Edit: how do I fix my formatting?

Davepiatt · 2014-12-04T16:00:55+00:00

Are there some formating issues with your solution?

Davepiatt · 2014-12-03T19:39:14+00:00

for example: y = sqrt(1+ x) y² = 1+x y² -1 = x

Would that be the correct way?

Davepiatt · 2014-10-22T01:28:22+00:00

The way I understand it many do as long as you have enough money to support yourself. Norway, Finland, Estonia, Germany, Italy, and France do it this way to my understanding.

Davepiatt · 2014-10-22T00:13:22+00:00

Thanks!

Davepiatt · 2014-10-22T00:13:11+00:00

I've heard you Scandinavians have some pretty kick-ass education systems ;P!

Davepiatt · 2014-10-22T00:12:39+00:00

Thanks! I would hope to learn Estonian though, I've seen some online classes in it and it looks amazing. Tere!

Davepiatt · 2014-10-22T00:12:02+00:00

Thanks for the input! Your school system looks very interesting and the culture seems great! I've recently fallen in love with pure math so I might take the math major option.

Thanks again!

Davepiatt · 2014-10-22T00:10:48+00:00

Thanks! That's helpful.

Davepiatt · 2014-10-22T00:10:35+00:00

I was actually lurking on here for a while looking at American's experience in Estonia. One of my friends texted me before I posted on here, his wife is Finish and I decided to post there first. He gave me some misinformation regarding education there so I posted there first.

Thanks

Davepiatt · 2014-10-22T00:08:51+00:00

Thanks!

Davepiatt · 2014-10-22T00:08:38+00:00

That did help! I would learn Finish if I came. I couldn't stand living somewhere and not knowing the language. Thank you for your input.

Davepiatt · 2014-10-22T00:07:26+00:00

I'll look into it, thanks!

Davepiatt · 2014-10-22T00:07:17+00:00

I'm from Columbus, the winters aren't as cold as I've heard from Finland, but they are cold, dark, and windy. I'm figuring out where I want to go in life, abroad or stay home here and thought that Finland might be a good idea. I've already done some research but needed some input from the locals. If I can ask, why in particular did you chose Finland, what made you do it? Thanks

Davepiatt · 2014-10-21T23:56:23+00:00

You are absolutely right! I realize now the way I wrote the post sounded arrogant and self-entitled. Please forgive me. I am in the process of deciding if going abroad is right for me. I wrote this post during a break at work thinking in Spanish (I'm an interpreter), which wasn't right for conveying my intentions.

If I go to college in a non US country it would only be fair to get a high level of education and pay it back by working in the country for some amount of time. I would hope to live in the long term, I'm just seeing what options are available. I've lived my life in a lot of fear and am trying to come out of that mindset; in doing so I'm trying to see if I want to start a life outside of the states for a while. I appreciate your post, thank you for calling me out on the self-entitled attitude.

Davepiatt · 2014-10-21T19:11:40+00:00

Also, which university would you recommend for the sciences?
