In this lesson, we will learn how to find the projection of a vector onto another.
Q1:
The cube shown has sides of length 4417. Find the scalar projection of 𝑂𝐴 onto 𝐶𝐵, giving your answer correct to two decimal places.
Q2:
𝐴 𝐵 𝐶 is a right-angled triangle at 𝐵, where 𝐴𝐵=17cm, 𝐵𝐶=11cm, and 𝐷 is the midpoint of 𝐴𝐶. Find the algebraic projection of 𝐴𝐷 in the direction of 𝐶𝐵.
Q3:
Given that ||=12A, ||=27B, and the measure of the angle between A and B is 60∘, determine the algebraic projection of (+)AB in the direction of ⃑𝐵.
