Question

Use the two given vectors to answer the following questions

u=3i-2j and v=7i +5j

convert the vectors into component form
find the angle formed between the two vectors

Answer 1

convert into components:

u=3i-2j

v=7i+5j

Step-by-step explanation:

so now we starting the question by multiplying to both vectors.

u*v = (3i * 7i) - (2j * 5j)

since i^2=1 and j^2=1

so,

u*v = 21 - 10

u*v = 11

i'm pretty sure!

Thank you!
