So......

I've actually been able to figure out #1-11. So, #12-15 are just sort of trippin me up. I've been able to set up the equations etc. but thats as far as I get on those

ok......

Im actually only having problems with 2, 5, and 7. Ive completed the rest.

http://hmco.tdlc.com/precalc/tdlc/www_precalc.htm#  Ok so this link should bring you to the questions index. i need help w/ 30, 48, 64 and 74

<-Link#30 (Magnitude=IIvII=3, direction=u=<4,-4>=4i-4j) What is the value of v?

<-#48(IIvII=3, u=3i+4j) What is the component form of v with the magnitude and angle in relation to the positive x-axis? How do I sketch this too?

<-#64(magnitude=70lbs, 40lbs, 60lbs; @-30deg, 45deg, 135deg)What are the direction and magnitude of the resultant vector?

<-#74(velocity=580mph @ N60degW, wind=SW @ 60mph)How do I draw a figure that gives a visual representation of the problem? and What is the true direction of the plane and what is the speed with response to the ground?

I hope you can click on the links to the left of the descriptions. :)

Thank you SO much! This helped ALOt!
