Sample Problem 18

Just to avoid confusion for everyone looking at this video, i think all the sins in this problem should be cosines and vise versa.
The angle theta given in this problem is the complement of the angle we usually have, i guess proff. krousgrill didnt look at that.

In case i m wrong pls let me know.
thanks

You are correct. When I drew my FBD, inadvertently changed the angle that I was calling theta. As you suggest, the sine's and cosine's need to be switched to make the analysis consistent with the angle theta give in the problem.

Thanks for pointing out this to us.
