Yes sir thank you for solving this problem but I have an another doubt that why in some books 1/0 is written as infinite but in some books it is written as not defined.😀😀😀 Please make a video on this topic.
Because if you improvise and start dividing numbers with 0 then many equations will formed by which all numbers will become equal to 0 and hence by this every number will be equal to each other by which our well formed number system will collapse and whole mathematical systems will collapse at 0. That's why any number divided by 0 is undefined.
@@sushmitabhanja7071 Not defined and infinite have the same meaning definite is the opposite of infinite so in some books there is written not defined.
let 1/0 =x or,1/x =0 It is only possible when x is approaching to infinity. bcz finite/infinite approaches to zero. therefore 1/0 which is equal to x and we have already proved that x is approaching to infinity. and infinity is termed as undefined.therefore 1/0 is undefined. thatswhy if u look in class 10th book value of tan 90° is undefined. bcz tan 90° = Sin 90°/ Cos 90° = 1/0. which is not defined. but in some book tan 90° = infinity. therefore undefined word is used in place of infinity. in some book.

Sir, can we find the square root of a negative number...
in complex no. square root of negative no. is defined as iota.
√-1 = i here "i" is pronounced as iota.
No ,
Suppose square root of √-4 = -2
But -2² = 4
( -2×-2 = 4 )
Since -. - = +
Therefore square root of negative number is not real number .
And the under real number all the number are there eg , whole , natural ,integer , rational , irrational .

@@edupoint.secondary Thank you very much sir. I am amazed to see your quick response. Thank you very much😊😊
Sir why 1 / 0 is infinity
let 1/0 =x
or,1/x =0
It is only possible when x is approaching to infinity. bcz finite/infinite approaches to zero.
therefore 1/0 which is equal to x and we have already proved that x is approaching to infinity.
and infinity is termed as undefined.therefore
1/0 is undefined.
thatswhy if u look in class 10th book value of tan 90° is undefined. bcz
tan 90° = Sin 90°/ Cos 90°
= 1/0.
which is not defined.
but in some book tan 90° = infinity.
therefore undefined word is used in place of infinity. in some book.
