Question 5: 10 pts

Write a with magnitude 10 and direction 42° in component form. Round to the nearest tenth.

Answer 1

6.7i + 7.4j

Explanation:

if the angle starts from the East (direction of positive x-axis)

then the y (j) component is 10*sin(42) = 6.7

and x (i) component is 10*cos(42) = 7.4
