For this question, the function given is fx equals to 1 upon 5 plus x, so whole square.
00:08
Now value of this function at x equals to 0, so this will be 1 upon square of 5 and first derivative of this function with respect to x, so that will be minus 2 upon 5 plus x whole cube.
00:24
Then finding value of this f dash at x equals to 0, so that will be minus 2 upon cube of 5 and finding second derivative of this function with respect to x, so this will be plus 6, 3 to the 6 upon 5 plus x to the power 4 and value of f double dash, that is equals to 6 upon 5 raise to the power 4.
00:51
Getting again with respect to x, so this will be minus 24, 5 plus x to the power 5, so its value at x equals to 0, so that is minus 24 upon 5 raise to the power 5 and so on.
01:10
Now the by maclaurin series, next will be so on, so by maclaurin series, this function will be written as fx equals to f of 0 plus x into f dash 0 plus x square upon 2 factorial f double dash 0 plus x cube upon 3 factorial f triple dash 0 and so on.
01:43
So, this will be 1 upon 5 plus x whole square, so this is equals to 1 upon square of 5 minus x into this is 2 upon cube of 5, here f naught, so f naught is square of 5.
02:04
Then on further simplifying, this will be plus, this will be plus x square 6 upon 2 into 5 raise to the power 4 and so on.
02:19
So, this series will be written as, this is equals to summation n equals to 0 to infinity minus 1 raise to the power n x to the power n and here it is n plus 1 upon 5 raise to the power n plus 2...
