Using half angles, solve these problems.

sin(22.5)

tan(15)

I really do not know how to do these at all. Could someone please show the work for these?

My 96 ford probe was running great until I took it to get inspected. It had failed emissions.

So they told me to change the one oxygen sensor. I did so and it still failed emissions. I was told the computer was bad. After a few weeks of searching, I finally found a computer and replaced it in my Probe. It passed!

But when i got it back I noticed a severe performance drop. It seems to have a real problem getting up to 30mph. After that it seems ok. But I mean it really struggles from time to time. Does anyone have any suggestions to what I could possibly do?

I know this is weird.

But I need as many pictures of anyone on cartoon network eating ice cream as you can find. Anyone know where I can find such images? Many even any cartoon character + ice cream.

well, i have recently bought another external harddrive.

Maxtor OneTouch 4 plus 750gb. And For some reason the data transfer is SOOO SLOWW it takes like 15 mins to transfer a 700mb movie. Now I have had this same problem with my 320gb external seagate harddrive. But the seagate seems to work fast on my upstairs computer..

Yes, i am using the 2.0 usb port and such. I just can't figure out why it is so slow.

suggestions?

Yes, a cookie packed with chocolate bars and marshmallows. I need a descriptive name that makes them sound WONDERFUL. which they are.

Ideas?

y = x^2 - 6x + 9; 2 <= x <= 4

Now when i did it, I ended up with an negative number. Which is impossible. I have no idea what i'm doing on this. suggestions?

Ok, really confused on this.

Find the equation for the tangent to the curve at the given point.

1. f(x) = x^2 + 5x ; (4,36)

Is it y = 13x-16? I have no idea.

Oh and.

2. Find the equations of all tangents to the curve f(x) = 1/(x+4) that have a slope -1.

What do I do for this?

Can someone explain this a little?

Find the derivative of y with respect to the independent variable.

1. y = 10^x

2. y = t^(9-e)

help please?

I can't remember how to do these problems!!!!

find dy/dx by implicit differentiation

1. 2xy - y^2 = 1

2. xy + x + y = (x^2)(y^2)

Can you kind of explain it to me? I'm so lost with y' and such.

Water is discharged from a pipeline at a velocity v given by v = 1628p^(1/2), where p is the pressure(in psi.) If the water pressure is changing at a rate of 0.323 psi/second, find the acceleration (dv/dt) of the water when p = 42.0 psi. Ideas?

Help please? THanks

A company is constructing an open-top, square-based, rectangular metal tank that will have a volume of 48 cubic ft. What dimensions yield the minimum surface area? Round to the nearest tenth, if necessary?

Ideas? help?

How do you do this? I'm at a loss. :(

Find the slope of the tangent line to y = e^(-2x) @ the point (0,1).

...

Ok I have a odd case.

I have a history of anorexia and ocd. In my previous treatment for the eating disorder, the doctor put me on prozac since i was experiencing some depression (20mg). I got out of treatment nearly two weeks ago and all together it's been about 8 weeks on prozac.

Here's the problem.

Over the past 3 or so days, I get really manic and super happy. It doesn't feel like normal happy. I go crazy, FULL of energy, racing thoughts, talk really fast (too fast sometimes that i don't even know what i'm saying), and just feel overpowered. Strong as an ox.

Now every once in awhile, I'll get hit with a random spell of depression, and everytime it happens, it's worse and worse. To the point that I don't care enough to move, I just lay on the sofa and stare into space. And at one point I have begun thinking a LOT about suicide. Pill overdose mostly.

But it only last maybe 3 hours tops then i'm HAPPY again. And occasionally, I have "NORMAL" moods, where I'm just well normal.

Can you explain this.

Find dy/dx if

y = 6^((5x^2)-1)

What do you do exactly? :/

find dy/dx if

y = (x^2)(2^x)

Ideas? :/

I got this problem here that I don't really understand. Could some explain it alittle and let me know what they got?

Find the derivative of y with respect to x, t, or 0, as appropriate.

y = e^(2sqrt.x + x^4)

that's 2 times the square root of x

Oh and while we are at it. For the same instructions, would the answer to...

y = e^(3-7x) be..

-7e^3-7x ?

THANK YOU :]

there's a few rare pokemon that i cannot get since i don't have any of the gba versions. So does anyone have an action replay that could trade me a few rare pokemon on d/p?

Please and thanks to any responses

I'm not looking for someoen to type me an essay or anything.

I just want to know what besides the compromise between the federalist and anti-federalist, lead to the growth of a federal system of government?

I have A LOT of coke points. And i'm really into pepsi right now, so if anyone is interested in trading, i basically have no limit, just lemme know, we can work something out

ok i found this monitor laying around. I hooked it up. And it seems to just come on for like 4 seconds then go to black. I tried running it as a secondary monitor and everytime i set to clone it goes to the screen for like 4 seconds. then boom. And i am setting it properly, since i have a projector that i use as a secondary.

I got the monitor literally from a junkyard, so what's wrong with it? Besides that i got it in the junk haha.
