What set of numbers are scalers precisely?  Most people often assume scalers to be real numbers only forgetting that a vector space can be defined over any field of numb…

Find the unit tangent vector at the point $(2,0,\pi)$ for the curve with parametric equations $x=2\sin\theta; y=3\cos\theta; z=2\theta$, we see that the point $(2,0,\pi)…

If $A=3i+2j-3k$ &B= 2i-2j-k$ $C=2i-j-3k$ What is $2C-[2A.(2B+4C)]B?$ We will be breaking down the solution one step at a time. First we begin with $2A=2(3i+2j…
