Could you please tell me how is a 420 degrees angle possible?

vinyassingh

why not???/ 420⁰ = 360⁰ + 60⁰ = 60⁰

becoz 360⁰=0⁰

See Dude

Such concepts that u are asking are wrong in one subject

Where as are right in other subject

The question u have asked is right in Physica whereas wrong

In maths some areas , Explaining u why

In maths The maximum u can go upto is 360 .

But this 360 is max in case of Geometry

Whereas as far as Algebra is concerned

u can go upto infinity

I can prove it - In algebra when we draw the graph

Of Sinx then the angle varies from (- infinity) to

(+infinity) so there is a possibility of 420 degrees.

Where as in Physics when it is said in case of cicular motion that

it has travelled distance of angle 7 pi / 3 then we say that it has

Travelled distance of 420 degrees.

Hope u understand.

plZ rate me for my efforts.
Cheers !!!!!!!!!@@@@@@@@!!!!!!!!!!!!!!!!!!!!!!

an angle is measured in anti-clock direction, and if the angle exceeds 360 degrees,divide with 360. so 420 when divided with 360 remainder is 60, the angle comes t first quadrant.so the trignometric values of 360degrees n 420degrees r same

if u want more explanation i can give

Dear,

its better if you post the complete problem then it will be easy for us to understand the context .However

waterdemon has done a good job. I hope it will be clear to you now.

Anyway if you have any doubt , please feel free to ask.
