It is not necessarily black.Because no light is reflected or transmitted, the object appears black when it is cold.

Consider (tan3x - tanx)/2

=1/2(( sin3x/cos3x)-(sinx/cosx))

=1/2((sin3xcosx-cos3xsinx)/cos3xcosx)

=(sin(3x-x)/2cosxcos3x)

=2sinxcosx/2cosxcos3x

=sinx/cos3x

Therefore we can say that sin3x/cos9x=(tan9x-tan3x)/2

sin9x/cos27x=(tan27x-tan9x)/2

we get

(sinx/cos3x)+(sin3x/cos9x)+(sin9x/cos27x)=(tan27x-tanx)/2

Nodal analysis (as far as i know)  is used to find the voltage [ potential difference] between nodes(points

where elements or branches are connected) in a circuit.It is used to determine the voltage or current at

any point in an electrical circuit
