What are the i j-components of a plane vector A of length 3, if it makes an angle
of 30o with i and 60o with j. Is the second condition redundant?
Thank you for the opportunity to help you with your question!
Technically, the second condition "60o with j" is the same as "30o with i".
See attached for the picture. the i component is ( 3 cos 30 ) i and j component is = (3 sin 30)j
