1. Determine the resulting tension in the rope and magnitude of **u** when theta = 30 degrees

2. Write the tension **T** in the rope and the magnitude of **u** as functions of theta

3. Determine the domains of the functions

4. Compare **T** and **||u||** as theta increases

I know that ||u|| = sqrt a^2+b^2 but I just don't know what the values of a and b are.

Thanks in advance!!!
