1) What is the component form of resultant of 4b⃗ −2a⃗ ? *first arrow is on top of b, and second one is on top of a*
a⃗ =⟨6,−2⟩ *arrow is on top of a*
b⃗ =⟨−5,2⟩ *arrow is on top of b*
Enter your answer by filling in the boxes.
2) What is the product of 3√6cis(π/8) and 2√5cis(7π/6)?
3) Divide 12(cos(7π/6) + i sin (7π/6)) / 4√6 (cos (3π/4) + i sin (3π/4))
I have the answers in the boxes, but I want to make sure they're right.
