    Simultaneous trig equations.

    How can this system of 2 equation
    { A.Cos(x)+B.Sin(x)=tan^2(x)-1
    { -A.Sin(x)+B.Cos(x)=tan(x)


    have the solution:
    <br />
A=-Cos(x)
    <br />
B=Sin^3(x)/<br />
   Cos^2(x)<br />
    Note:The Second Solution is Sin^3(x) divided by Cos^2(x)
    Thanks for Help
