What is the angle between a=(1, 0, 0) and b=(1, 0, 0)?
a=(1, 0, 0), b=(1, 0, 0) के बीच angle क्या है?
Show answer and explanation
Correct Answer
C. 0°
ExplanationStep 1: Identify the concept: angle between vectors. Step 2: Use a·b=|a||b|cosθ to find the angle. Here θ=0°. Step 3: Exam tip: If dot product is zero, vectors are perpendicular.
Step 1: अवधारणा angle between vectors है। Step 2: a·b=|a||b|cosθ से angle मिलता है। यहाँ θ=0°। Step 3: याद रखें: Dot product zero हो तो perpendicular vectors।
