The question says : "Identify the ordered pairs on the unit circle corresponding to each real number t. Write your answer as a simplified fraction if necessary."

In this question t = -21pi / 4. they are asking me to correspond to the point (x,y).

Im really confused about how to proceed. I keep getting the questions wrong because of the sin/cos stuff. I dont know how to translate the fraction into sin/cos.

An airplane is traveling 835 km/h in a direction 41.5 degrees west of north.

(a) Find the components of the velocity vector in the northerly and westerly directions.

(b) How far north and how far west has the plane traveled after 1.75h?

I really dont understand this problem at all. An explanation of how to do the problem, and -why- were doing it like this would be nice. I need an understanding so I can do it without thinking twice.

Thank you very much.

Im 18 and about to go to a community college and I wanted to play baseball. Why not play at the community college before I transfer over. I really want to be either a pitcher or a catch(unlikely I know). Ive been practicing my pitcing whenever my shoulder allows. I want to know any credible programs for pitchers that you know of.

Im 18 and 5 7". My dad is 5 10" and my mom is 5 6". Do you guys think there is a possibility that I will grow anymore? Possibly 5 10"?

Im 18 5'8" 150lbs. I can still grow but Im taking MMA. Im wondering if someone larger tried to pick on me would my Muay Thai, BJJ, and Judo help me beat them? I know size isnt everything in a fight but its a big part.

I was reading a magazine the other day and the virtual reality headset, Oculus Rift seemed interesting. I have a knack for electronics but Ive read we only design circuitry and things. I want to have the ability to built things like computer, gaming systems, or even the next big innovation in technology. It seems like like all the inventors are Mechanical Engineers. Are these things I can achieve with Electrical/Computer Engineering?

Kickboxing? BJJ, Boxing? I just want something that if it ever did some to violence I could defend myself.

There are two MMA gys in my city and I going to go try it out in a few weeks. What are some signs of a "mcdojo"? One place offers Kickboxing and BJJ, the other Taekwondoe, Boxing, and BJJ.

I hear a lot of talk about how a kickboxers punches are lack luster, is this true?

I love kickboxing but I dont know if Ill have enough time to do what I love while going to school.

I know a lot of people say wrestling or kickboxing...what do you guys think?

I cant wait I need to read the manga.

Im an 18 yr old 5'9 male.

Im practically 18 and I think I really want to do a martial art. Im 5'9 with a slim build and long arms. Is it too late to start a martial art and become really good at it? I have the talent because I tried it when I was a kid.
