## natnatwebb 2 years ago Find the components of a vector u with magnitude 10 and direction angle theta=54 degrees.

FOR X COMPONENT Ax=Acosx where x is angle for Y COMPONENT Ay=Asinx

2. natnatwebb

So there will be two equations. One to find the Y value and one for the X value.

Yes and these two values are called components.

4. natnatwebb

Okay, lemme throw those numbers into a calculator...

5. natnatwebb

they're both .5 which isn't anywhere near the right answer...is there another step?

whats the answer of x component?

7. natnatwebb

0.58778525229

and what you are getting?

9. natnatwebb

thats what I'm getting...did i miss a step?

11. natnatwebb

Oh sorry, \[u _{x}=5.9\]

whatss up?

13. natnatwebb

and \[u _{y}=\]

14. natnatwebb

8.1

math processing error?

16. natnatwebb

I'll go get a different calculator but i dont think so. Give me a second.

17. natnatwebb

I still get the same answer.

the answer i am getting for x component is 5.87 and for y component is 8.09

19. natnatwebb

I must be missing a step.

may be you don't multiply 10.

which is A=10

22. natnatwebb

yeah missed that part. :) lol well that fixes all the numbers nicely.

23. natnatwebb

:D sweet, glad it was such a simple fix. Thanks a lot for your help!

25. natnatwebb

Yup.
