This one.. no guess work.. 
first i advice you to draw it out!

anonymous · Answer

@Mashy Listen, i understand that you are trying to help me grab the concept of it. But I havent had experience in ICP in 2 years. I don't even know how to do that. There are no lessons involved on this online class credit.

anonymous · Answer

@Mashy I'm really just looking for an answer so i can just get the hard ones out of the way and do the ones i can.

anonymous · Answer

thats ok.. i ll help you out. can you try to make a drawing of it? :)

anonymous · Answer

@Mashy I wish i knew how to try and draw it.

anonymous · Answer

I am sorry, but just giving answers won't do any good.. its against my policy and i am sure all mentors here will agree with me.. that is not the purpose of this site!! Don't take it the wrong way, but this is a study forum, and you can only expect people to help you out, but not give you direct answers. And I expect you to do the same when you are answering someone else's answer

now if you are ready to LEARN, i am here to help you and spend time with you (which you should appreciate, cause its free :P)
but if not, then i can't help you!

anonymous · Answer

@Mashy  Well then prepare yourself to do a lot of teaching because i do not know anything about anything in this ICP Lesson.

anonymous · Answer

I've also only got 14 minutes left to finish this pretest.

anonymous · Answer

I have an obligation to teach.. and your time constraint is really something i can't help you wiht

so i want you to quickly make a rough drawing
a vector making an angle q with the x axis..

anonymous · Answer

just draw co-ordinate axes.. and draw a vector (a line with arrow mark) FROM THE origin making an angle q with x axis.. come on.. give it a go!

anonymous · Answer

you can use the draw tool here!

anonymous · Answer

ll draw the co ordinate axes for you|dw:1395063659319:dw|

just hit edit and draw a nice vector

anonymous · Answer

time is a short.. quick man!

anonymous · Answer

I still don't know how to draw or what a vector is.

anonymous · Answer

This is pointless.

anonymous · Answer

you don't understand that i don't undersatnad or know anything about icp they just give me lessons after lessons and it is stressful.

anonymous · Answer

No explanation. Just tests. And its a "hopefully i pass this"
