Let 0 < α < 
be fixed angle. If P = (cos θ , sin θ ) & Q = {cos ( α – θ ), sin ( α – θ )}, then Q is obtained from P by-
A
Clockwise rotation around origin through an angle α
B
Anticlockwise rotation around origin through an angle α
C
Reflection in the line through origin with slope tan α
D
Reflection in the line through origin with slope tan 
Text Solution
Verified by ExpertsThe correct answer is:
D
∴ Point Q is the reflection of point P w.r.t. line through origin
with slope tan
