Hi, in this question here they gave an e power 0 .5x is equal to 5 minus 5x.
00:05
That f of x is equal to e power 0 .5x plus 5x minus 5 and differentiating this we get that f dash of x is equal to 0 .5 e power 0 .5x plus 5.
00:15
So here the tablet column x of x and f of x 0 is minus 4 1 is 1 .6487.
00:23
So f of 0 is minus 4 less than 0 and f of 1 is 1 .6487 greater than 0.
00:27
Therefore, the root lies between 0 and 1 x not is equal to 0 plus 12 which is equal to 0 .5 that is x not is equal to 0 .5 and moving on to first iteration.
00:39
In first iteration f of x not is equal to f of 0 .5 which is equal to e power 0 .25 plus 5 .0 into 5 .5.
00:49
So this is equal to minus 1 .216 and f dash of x not is equal to f dash of 0 .5.
01:00
This is equal to 0 .5 e power 0 .25 plus 5 which is equal to we get that 5 .642 x 1 is equal to x not minus f of x not into f dash of x not.
01:14
So x 1 is equal to 0 .5 minus 1 .2165 .642.
01:21
So therefore we get x 1 is equal to 0 .71 double 5 and second iteration is f of x 1 is equal to f of 0 .71 double 5 which is equal to e power 0 .3578 plus 5 .0 into 0 .71 double 5 minus 5 which is equal to 0 .0077 and f dash of x 1 is equal to f dash of 0 .71 double 5 which is equal to 0 .5 e power 0 .3578 plus 5 is equal to 5 .7151...
