e^{ix} = cos(x)+i·sin(x)

e^{(-i)x} = cos(x)+(-i)·sin(x)

(x+iy)·(x+(-i)y) = x^{2}+y^{2} = 1

e^{ix} = cosh(ix)+sinh(ix)

e^{(-i)x} = cosh(ix)+(-1)·sinh(ix)

(x+y)·(x+(-1)y) = x^{2}+(-1)·y^{2} = 1

cos(x) = 1+(-1)·(1/2!)·x^{2}+(1/4!)·x^{4}+(-1)·(1/6!)·x^{6}

cosh(ix) = 1+(1/2!)·(ix)^{2}+(1/4!)·(ix)^{4}+(1/6!)·(ix)^{6}

i·sin(x) = ix+(-i)·(1/3!)·x^{3}+i·(1/5!)·x^{5}+(-i)·(1/7!)·x^{7}

sinh(ix) = ix+(1/3!)·(ix)^{3}+(1/5!)·(ix)^{5}+(1/7!)·(ix)^{7}

m·d_{tt}^{2}[x(t)] = (-1)·a·( x(t) )

(m/2)·d_{t}[x(t)]^{2} = (-1)·(1/2)·a·( x(t) )^{2}

x(t) = cos( (a/m)^{(1/2)}·t )+i·sin( (a/m)^{(1/2)}·t )

x(t) = cosh( (a/m)^{(1/2)}·it )+sinh( (a/m)^{(1/2)}·it )

x(t) = cos( (a/m)^{(1/2)}·t )+(-i)·sin( (a/m)^{(1/2)}·t )

x(t) = cosh( (a/m)^{(1/2)}·(-i)t )+sinh( (a/m)^{(1/2)}·(-i)t )

x(t) = cosh( (a/m)^{(1/2)}·(-i)t )+sinh( (a/m)^{(1/2)}·it )

x(t) = cosh( (a/m)^{(1/2)}·it )+sinh( (a/m)^{(1/2)}·(-i)t )
