Feedback refers to the response given by the receiver of a message to the sender. It is a critical component of the communication process as it ensures that the message has been understood as intended.
Importance:
1. Clarity: Feedback helps clarify any doubts or misunderstandings, making the communication process more effective.
2. Improvement: It allows the sender to refine their message or approach based on the receiver's response.
3. Encouragement: Positive feedback boosts the sender’s confidence and encourages better communication.
In summary, feedback is a two-way process that facilitates better understanding and connection between the sender and receiver.
In the adjoining figure, TP and TQ are tangents drawn to a circle with centre O. If $\angle OPQ = 15^\circ$ and $\angle PTQ = \theta$, then find the value of $\sin 2\theta$.
