1. If a (5, 4), and b= (-3,2), calculate: (i) 2a + band (ii) 3(b-a) 2. Write the horizontal and vertical components of these vectors. Write your answers in exact form where possible: (i) Magnitude 2, angle of 60 with the x-axis; (ii) Magnitude 10, angle of -60 with the x-axis (iii) Magnitude 4, parallel to the y-axis. 1.
