Thank you for the correction sammy, I'm not very good at vector calculus, and my book is hard to get useful information from. so, I have u(hat) = (2yi + 2xj)/(sqrt(4x^2 + 4y^2)) and v(hat) = (2xi -2yj)/(sqrt(4x^2 + 4y^2)) I still do not understand how to take the time derivatives though...

Homework Statement The Hyperbolic coordinate system is given by: u=2xy and v=x^2 - y^2 a.) Find the unit vectors u and v in terms of u,v,x(hat),y(hat) b.)Find the time derivatives of u(hat) and v(hat), your answers will have du/dt and dv/dt in them Homework Equations None really...
