This is Calculus course especially about vectors. I need help with some questions. I also attached formula sheet in case you need it as a reference.

6. A boat on a lake is heading at a bearing of 40. The boat is traveling at a velocity of 40 km/h and the current is flowing from the southeast at 9 km/h. Determine the heading of the boat and the resultant velocity relative to the ground. [4 marks] 7. PQRS is a parallelogram shown below. Points T and W are the midpoints of PS and QR, respectively. If PQ=u and TS =v, express the following vectors as linear combinations of u and v .
