Daily DAX : Day 369 SIN

📐SIN Function in Power BI DAX

🔍 What is SIN?

SIN(angle) calculates the sine of an angle (in radians).

SIN(0) = 0 | SIN(π/2) = 1 | SIN(π) = 0 | SIN(3π/2) = -1

📝 Syntax

SIN(<angle>)
• <angle> = Number (in radians)

⚙️ How to Use

Example	Formula	Result	What it does
45°	SIN(RADIANS(45))	0.707	Sine of 45°
90°	SIN(RADIANS(90))	1	Sine of 90°
Column Data	SIN(RADIANS([Angle]))	Calculated	Apply to each row

🎯 Real Use Cases

Use Case	Formula Example	Business Value
📏 Distance Calc	SIN(RADIANS([LatDiff]))	Calculate distances between locations
📈 Wave Patterns	SIN(RADIANS([Time]))	Model seasonal sales trends
🔧 Engineering	SIN(RADIANS([Angle])) * [Force]	Calculate force components
📊 Trigonometry	SIN(RADIANS([Degrees]))	Geometry calculations

🚀 Quick Start Steps

1. Convert Degrees → Radians: Use RADIANS([Degrees])
2. Create Measure: SineValue = SIN(RADIANS([Angle]))
3. Visualize: Add to Line Chart for wave patterns

⚠️ Pro Tips

• Always use RADIANS() for degree inputs!
• SIN returns values between -1 and 1
• Combine with COS() for complete wave analysis
• Great for time-series forecasting
