Use the definition of scalar product, a · b = |a||b| cosθ, and a · b = axbx + ayby to calculate the angle in degrees between the two vectors a = 3.0i + 3.0j and b = 4.0i + 2.0j.
Added by Chelsea A.
Step 1
Vector a = 3.0 i + 3.0 j can be written as (3.0, 3.0). Vector b = 4.0 i + 2.0 j can be written as (4.0, 2.0). Show more…
