logA+logB+logC=logABC

logSin+logCos+logTan=log sin cos tan

but

tan=sin/cos

so

log sin cos tan=logsin cos (sin cos)

log sin cos tan=sin²

by identity,

sin²=1-cos²

so

log sin cos tan=log1-(√99/10)²

log sin cos tan=log1/100

so answer is

=logsinx*cosx*tanx

=logsinx*cosx*(six/cosx)

=logsin^2x

=log(1-cos^2x)

=log(1-99/100)

=log(1/100)
