Hello everyone! I have a worksheet and it says Graph the following limits: (i) r(t) = <t,-t,t^2>; (ii) r(t) = <t,sin t, cos t> can that be transformed into a unit vector? like r(t) = ti - tj + t^2k? & r(t) = ti + sin (t) j + cos(t)k I'm confused on what he wants!

I'm supposed to sketch this graph \vert x \vert + \vert y \vert = 1 + \vert xy \vert I think the purpose of the exercise is to simplify this into something that resembles a typical function and be able to shift the graph over so that it looks normal. I'm having troulbe getting the y's...

I am graphing a parabola for a calculus problem. I understand how you factor and use the two x values as your x-intercepts, but I'm not sure how this one would be graphed. y=4x^2 - 25. I understand how the vertex of the parabola would be at negative 25, but I have no clue what to do woith...
