Find the equation of the line tangent to the curve xy^{3}+xy=20 at the point (10,1).

When the equation of this tangent line is written in the form y=mx+b

Step 1

It is given that, the equation of the curve is* xy*^{3}* + xy** = 20.*

Use implicit differentiation to differentiate the above function with respect to *x*.

Step 2

On further simplification,

Step 3

Substitute the point *(10, 1)* in ...
