00:00 - 00:59 | hello everyone the questions is that determine the value of the constant am so that the function f x is equal to M into x square - 2 x x 0 and cos A is equal to zero is continue it is given continue to what we will do let find when X is less than zero so limit access less than zero less than to exchange 20 - effect this is your talking about Allah it is going to give us limit action shoe 0 - m into x square - 2 x Nifty put the value it is going to give us m0 -0 which is actually going to be zero |

01:00 - 01:59 | and when we talking about limit extensor zero Plus Yahan to check left hand side limit and right inside living and country was given that means both should be equal if we put that limit x x 20 + cos x 80 gives us 1 from here we can say that the left hand side limit is not equal to right hand side limit this can say that 4 clearly that the airport affects is discontinuous at X equal to zero also if you have to find the value of m so |

02:00 - 02:59 | if we see here that whatever value at X equal to zero is going to be x 0nly so from here we can say that I am can be any value and can be any value but at last it is going to be zero only the product of zero it is going to be honest and can be any value 123 |
