Solve Find the angle between vectors a = (-3, 5) and b = (0, 1). — Step-by-Step Solution by AhaStep

📝 Problem

Find the angle between vectors a = (-3, 5) and b = (0, 1).

1. 📝 Summary: v = (0$ , 1)

2. 🧮 Dot Product: u · v = 5

3. 📐 Magnitudes: |u| = 5.830951895, |v| = 1

4. 🎯 Angle: cos(θ) = (u·v)/(|u|·|v|) = 5/(5.830951895·1) = 0.8574929257
