The point is (1,1,3). But for u, t = 3, and for v, t = 4. So, do I use one of those t-variables, or go with something else entirely?

Great, thanks! But when I actually do out the equation, I have all of those "t" variables everywhere (2t+1) - (3t^3), etcetera...what do I substitute in for that?

Homework Statement Quick question. I need to find cos \vartheta, where \vartheta is the angle (acute) between two vector-valued functions (which are tangent lines).Homework Equations I think this is relevant: cos\vartheta = (u dot v)/(\left\|u|| * \left\|v||) The Attempt at a Solution Is...

how do i do that?

Homework Statement Point A (3,2,-1) is equidistant from two planes (parallel), known as P1 and P2. P1 has the equation 2x-y+2z+4 = 0. Find the equation of P2. Homework Equations D = abs val(ax_o + by_o + cz_o + d) divided by sqrt (a^2 + b^2 + c^2) The Attempt at a Solution I...

Homework Statement There is an RC circuit with a 6 V battery, a 100 Ohm resistor, and 2.0 microFarad capacitor. At time t = 0, the switch is closed. While this happens, an ammeter measures the current through the resistor. At t = 0.000139 s the ammeter finds that 0.030 A is flowing through...
