Use implicit differentiation to find an equation of the line tangent to the curve sin(x+y)=2x-y at the point (pi, 2pi )
We are given equation as
we can find derivative with respect to x on both sides
we can solve for y'
now, we can plug back x=pi and y=2pi
so, slope is undefined
so, tangent line is vertical line
so, the equation of tangent line is
