The intersection of L3 and L4 is at (x=1, y=1, z=1). Could you try asking your questions with sentences. You're kind of like a deaf-mute who can only point and grunt.

Most of the books I used for learning this stuff are approaching half a century old and therefore not likely to be available. The one exception to that might be the Feynman Lectures which are now available online. Chapters 1-3 of Volume II cover most of the vector algebra and calculus you might require.
