Homework Statement
4.9b cites the y components to be sin degree and 4.9a is somehow cos degree for the x components (see picture)
Homework Equations
Here's a different textbook that supports my claim (see picture)
The Attempt at a Solution
Shouldn't the y components for problem 4.9b be cos instead of sin based on how the angle of the vector is oriented? Isn't this vice versa for problem 4.9a (this should be sin)
