Dot Product
6 문제점
문제 1객관식
Two vectors a and b are given. Determine the dot products a ⋅ b and a ⋅ a:
a = i + 29j, b = 15i + j
문제 2객관식
Two vectors a and b are given. Determine the dot products a ⋅ b and a ⋅ a:
a = 11i - 3j, b = -10i - 8j
문제 3객관식
Find a ⋅ b + a ⋅ c using the following vectors:
a = 9i - 4j, b = i + 5j, c = 8i + 3j
문제 4객관식
Are the vectors a and b orthogonal?
a = 12i - 6j, b = 5i + 10j
문제 5객관식
Determine the projection of vector a onto vector b. Next, express vector a as vectors, a1 and a2, where a1 is parallel to vector b and a2 is perpendicular to vector b.
a = 11i -j, b = 3i +9j
문제 6객관식
Find the angle between the two vectors. Express the angle in degrees and round it to two decimal places.
