Hello students.
00:01
Today we will discuss about this question.
00:04
In this question, we are given that y plus 2x cube, that is to natural log of 2x square y.
00:12
We need to find y -dust, that means y, divide it by dx is equal to question mark.
00:18
And then we are given that the measure of side square, that is 3 unit, with a possible error, that is equal to 0 .03 unit.
00:35
We need to estimate the possible error made in measuring area.
00:40
So we need to find the area da and we are given dx that is equals to 0 .0 and we are given x that is equals to 3 units.
00:53
So here first of all we will find y -des.
00:56
So therefore, y plus 2x that is equals to allen of 2 x squared y.
01:03
So that implies that d divided by dy divided by dx plus 6x squared that is equals to 1 divided by 2x squared y multiplied by d divided by dx of 2x square y...
