In this lesson we talk about how to find the x and y components of a vector given its magnitude and direction, by drawing a right angle triangle with the x axis and using trigonometry.
This is a dynamic resource which will continuously be updated with the aim of creating the ultimate resource you need to be plant based. 這是一篇隨時會更新的資源，以便想要吃素的人參考。 In order to encourage more people to follow the plant based movement, I will regularly share some photos of what I eat, so you can see that food can be …
In this lesson we talk about – Given a position vector, how to find its magnitude. – Given a position vector, how to find its direction (as a compass bearing).

In this lesson we define unit vectors i and j as vectors moving along the x or y axis with a magnitude of 1. Then we define position vectors using unit vectors.

Today we discuss what scalar multiplication means for vectors, and we do some addition / subtraction examples combined with scalar multiplication.
Why am I showing a picture of white rice? Doesn’t rice make you fat? Isn’t white rice not as good as brown rice? Here is Doctor John McDougall’s advice on white rice. In this video he explains why white rice is okay, and that he tells his patients to eat rice and vegetables. 為什麼我照一張白飯的照片? 吃白飯會變胖不是嗎? 這是美國醫生McDougall對吃白飯的建議，他認為吃白飯是好的，並且他說為什麼他要他的病人吃白飯跟蔬菜。 This is …
