Why Radian intead of dgree? Can anyone explain why we always use radian instead of degree?

Thank you!

I am working on it. Do I have to change degree to rad?

Ok, Guys I received two warning messages because I posted my own Opinion. I shall respect the rules of the forum and will not put my personal opinion any more!

Science is the subject where opinion and speculation really matter! Where is your evidance to disprove me. Do not just say 'there are theories'! wheer are they?

Believe me in some culture people still using position of shadow caused by Sun. This is the most common practice t predcit the paryer time. you may be aware of the fasting month, there is sun can be used as time clock.

Vx= Vcos theta and simailry Vy= Vsint heta can be used here.

No one actually knows when the world will end and even not wise to know!

In a simple logical way for the big bang to be happen, we need mass, energy and space. Where they come from? obvoisly it was there before the big bang, clearly Big bang is not the start of the universe then? Even the law of nature were existed before the big bang!

It means if you apply a force of mass 1 Kg and that body traveled a disatnce of of one meter and takes two seconds, it means the applied force is one Newton. i.e 1N= 1Kgm/s^2

What are the things that you do not undersatnd? Mathametics is logical and practical subject.

When force multiplied for short inetrval of time. i.e I= F* dt or I=dP
