d/dx(uv)=u*dv/dx+v*du/dx
d/dx(secxtanx)=secx*[d/dx(tanx)]+tanx*[d/dx(secx)]
-The derivative of tanx is:
d/dx(tan u)=[sec(u)]2*d/dx(u)
d/dx(tan x)=[sec(x)]2*d/dx(x)
d/dx(tan x)=[sec(x)]2*(1)
d/dx(tan x)=(sec(x))2=sec2(x)
-The derivative of secx is:
d/dx(sec u)=[sec(u)tan(u)]*d/dx(u)
d/dx(sec x)=[sec(x)tan(x)]*d/dx(x)
d/dx(sec x)=[sec(x)tan(x)]*(1)
d/dx(sec x)=sec(x)tan(x)
d/dx(secxtanx)=secx*[sec2(x)]+tanx*[sec(x)tan(x)]
d/dx(secxtanx)=sec3(x)+sec(x)tan2(x)

Prove that a constant vector always has a perpendicular derivative?
A dot A = A2 do a derivative of both sides derivative (A) dot A + A dot derivative(A) =0 2(derivative (A) dot A)=0 (derivative (A) dot A)=0 A * derivative (A) * cos (theta) =0 => theta =90 A and derivative (A) are perpendicular
