Given:

The angles are in AABC in ratio 1:1:2.

To find:

The value of \frac{sec A}{cosec B} -\frac{tanA}{cotB}.

Step-by-step explanation:

A+∠B+∠C=180^{0}

x+x+2x=180^{0}

4x=180^{0}

x=45^{0}

Thus,∠A=x=45^{0},∠B=x=45^{0},∠C=x=90^{0}.

\frac{sec A}{cosec B} -\frac{tanA}{cotB}

=\frac{\sqrt{2} }{\sqrt{2} } -\frac{1}{1}

=1-1

=0

Answer:

Therefore, the value of \frac{sec A}{cosec B} -\frac{tanA}{cotB} =0.
