GIVE REASON :

X/0=∞ ( INFINITIVE )

ALSO TELL, WHY THE FOCAL LENGTH OF PLANE MIRROR IS INFINITIVE?

Answer 1

Okay

X/0= infinite

because

X can be a number:

1. Natural

2. Integer

3. Real

4. whole

5. Complex

Okay

so if we divide

any type of number

with 0

We get infinite

To prove it

Let's do something

(X/0)

MULTIPLY 0/0

(X/0)×0/0

=0/0

SIMPLY here we can say that

y/y is 1

but 0/0 is not because

because if MULTIPLY any number to 0 we will get 0 so but x/y can be only one number in SIMPLEST form.

.........-2,-1,0,1,2,3,4,5,6,7,8.....

so 0/0 is every number

As it is every number

it is undefined

so it is shown by infinite.

Focal length of plane mirrors is considered to be infinite, as the radius of curvature is infinite. However, imagine this scenario: You have a perfectly flat (this is theoretical)plane mirror, and the earth is perfectly flat as well(theoretical).
