Explain the Communication Cycle in detain with Example in simple way !!!

The Communication Cycle consists of following elements :

1) Sender

2) Receiver

3) Message

4) Feedback

1) Sender : A person who transfer his ideas, thought, information, Feelings, to the other person is known as sender.

Example. i) The teacher teaching English chapter in the class.

ii) Ramesh demanding sevpuri from his mother.

2) Receiver : The person who accepts the message from the sender is called as or known as receiver.

For an example. i) Father is giving money to Rohan.

ii) Sohan listen speech on the independence day.

3) Message : The thoughts and ideas exist in the mind of the sender in the form of instructions, feelings, knowledge, information.

Than the sender organize this thoughts and ideas in the proper format to be transfer to the receiver is called as message.

For an example. i) Rahul is asking maths notebook to Naresh.

ii) Sita demanding apple from his mother.

4) Feedback : The feedback is the most important and final link of the communication. If feedback is not there than communication cycle will not complete.

It is the most important factor in the communication cycle.

For an example. i) The teacher is asking question to Amit.

ii) Meets is asking for red pen to the father. {If father have pen than they will give it to her}.

If sinθ = 7/25, find the values of cosθ and tanθ || Trigonometry sum || by SCIENTECHPLUS

 

Watch in this above given video, you know the complete solved sum easily.

If sinθ = 7/25, find the values of cosθ & tanθ ?

Ans :  By using formula - sin²θ + cos²θ = 1

cos²θ = 1 - sin²θ

cos²θ = 1 - (7/25)²

cos²θ = 1 - (49/625)

By using L.C.M (Least Common Multiple)

cos²θ = (625/652) - (49/625)

cos²θ = (625-49)/625

cos²θ = 576/625

Here we get cos²θ but we want cosθ value, so therefore 

we want cos²θ to cosθ, for that this square on the cos²θ goes on the Right side of the = sign and become square root.

cosθ = √(576/625)

Therefore   cosθ = 24/25

But we have to also, find the tanθ by using formula tanθ = sinθ/cosθ

So in the given formula, put the value of sinθ and cosθ.

tanθ = (7/25)/(24/25)

So the value of tanθ = 7/24
