**Urgent SUMMER SCHOOL CALCULUS**

Add these two vectors: I used component law, and I got an answer, but I am unsure as to how to do the direction at the end. Add: 9m/s [N30E] and 2m/s [N60E] I wound up with 10.8m/s and I found an angle of 55 but I am unsure as to what do with the 55: thanks for the help, I ...

Is that your actual thesis statement? And in addition, do not use personal words (I, me, we, us,) and only refer to things as she, he, it, they, after you have specified what you are discussing (just on a side note). Ok, so your thesis statement should be more like: Shoe ...

**URGENT SUMMER SCHOOL CALCULUS**

My diagram doesn't work out, I have done it to scale, but I can't figure out how to draw it. I got the same answers as everyone above, I used the cosine and sine law to do mine (I got my answer after I posted :) ). But my diagram looks weird. Any thoughts?

A force of magnitude 15 N is the resultant of two forces, one of which has a magnitude of 8 N and acts at an angle of 30° to the resultant. Find the magnitude and direction of the other force...how do I begin to solve this!?

I think the answer would be 10.8m/s [N35E]. Am I correct?

Another one for you :P, add these two vectors using trigonometry (again)... 9N[S2W] and 11N[N31W]...Again, I am confused about the angles, I am not sure what value I should use for the cosine and sine law. THANKS AGAIN!!

Add the following vectors , 7m/s [N30E] and 2m/s [S17E], using trigonometry. Once you draw these out into diagrams, you use the triangle law yes? How do you find the angles to use in the cosine and sine law? A little confused, thanks for the help.

I used the sine law to get 15 degrees. I am unsure as to what I now do with this angle. Do I add or subtract it somewhere to find the overall angle I am looking for? Thanks again! I owe you!

Thanks! I agree about the components but the question said specifically to use cosine and sine law :(. Thanks very much though!
