Re: Find the unit tangent vector T(t)
i am having one idea i.e first obtain locus of above coordinate system
x^2/3 +y^2/3=16 now obtain dy/dx for this curve that comes out to be -tan(t)
now obtain equation of tangent to this curve
but what i understand that you want to apply concept of gradient in above problem but that always gives equation of normal
