ACCORDING TO EQUATION OF CURVE,
![\[\surd x\text{ }+\text{ }\surd y\text{ }=\text{ }4\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-ac63202ce5682ff25bd87eee8f75b3d8_l3.png "Rendered by QuickLaTeX.com")
Presently, let (x1, y1) be he required point on the bend
SO ,
![\[\surd x1\text{ }+\text{ }\surd y1\text{ }=\text{ }4\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-fb987573c6741d5ff5c468025f41ad6f_l3.png "Rendered by QuickLaTeX.com")
separating both the sides w.r.t. x1, we get
squaring both the sides, we get
![\[y1/x1\text{ }=\text{ }1\Rightarrow y1\text{ }=\text{ }x1\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-27e65d58788799098a321a2eb024c8a7_l3.png "Rendered by QuickLaTeX.com")
PUT THE VALUE OF Y,
![\[\surd x1\text{ }+\text{ }\surd x1\text{ }=\text{ }4\Rightarrow 2\surd x1\text{ }=\text{ }4\Rightarrow \surd x1\text{ }=\text{ }2\Rightarrow x1\text{ }=\text{ }4\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-96602befcd90aace08a2d502c648ff9c_l3.png "Rendered by QuickLaTeX.com")
![\[As\text{ }y1\text{ }=\text{ }x1\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-503cb7dc551d4342cdf64dbf1eaf6bef_l3.png "Rendered by QuickLaTeX.com")

NOW ,
point is
![\[\left( 4,\text{ }4 \right).\]](https://www.learnatnoon.com/s/wp-content/ql-cache/quicklatex.com-7f4e96a4c53fdc80fa797684a3007282_l3.png "Rendered by QuickLaTeX.com")
