Hence F is conservative so there exists a function f such that ∇ f= F. Then f_x(x,y)=e^xsin y implies f(x,y)=e^xsin y g(y) and f_y(x,y)=e^xcos y g' ( y ). But f_y(x,y)=e^xcos y so g' ( y )=0⇒ g(y)=K. Then f(x,y)=e^xsin y K is a ...

The use of celebrityendorsements is commonplace in the USA, but little is known about its effects in the UK. This researchalso aims to incorporate the use of celebrity endorsements in political party advertising with thepolitical salience construct. Political salience represents how prominent politics ...
Determine whether or not {eq}F {/eq} is a conservative vector field. If it is, find a function {eq}f {/eq} such that {eq}F = \nabla f {/eq}. a.{eq}F(x, y) = (xy + y^2)\hat i + (x^2 +...
Find a function f such that {eq}F = \Delta f {/eq}. If the vector field is not conservative, enter NONE. {eq}F \left ( x, y, z \right ) = y \cos \left ( xy \right ) i + x \cos \left ( xy \right ) j - 6 \...
The way to recover is not to double down with Treasury austerity, new taxes and higher taxes. The way to recover is to live the dream, restore the brand – being a Conservative is all about backing people to succeed, getting out of the way of those who can do well and offering appropr...
