In geometry, the tangent line (or simply tangent) to a plane curve at a given point is the straight line that "just touches" the curve at that point. Informally, it is a line through a pair of

Newton's Method
Use the mouse to move the point A to the desired location for the first approximation to a root of f(x). Then click the "Newton's Method" tool (it looks like a wrench and screwdriver) and use it to
find the next approximation. See direction for using the tool in the hints area of the toolbar.

law of impulse
so mv=[itex]\frac{E}{c}[/itex], right?
No, since the general expression for momentum is related via:
[tex] E^2 = p^2c^2 + m^2c^4 [/tex]
So for massless particles (as the photon):
[tex] P = E/c [/tex]
There is no way that you can get mv = E/c
