1. aum

$$u\cos(\theta)i + u\sin(\theta)j$$

2. abannavong

im confused what does tht mean?

3. aum

Substitute u = 4 and $$\theta = 119$$ in the above equation and simplify.

4. abannavong

oh ok thanks

5. aum

The x-component of the vector is $$(u\cos\theta)$$. The y-component of the vector is $$(u\sin\theta)$$.
