‌விள‌க்க‌ம்:

\tan 45^{\circ}=1

cosec 30^{\circ} = -2

\sec 60^{\circ}=2

\cot 45^{\circ}=1

\sin 90^{\circ}=1

\cos 0^{\circ}=1

\frac{\tan 45^{\circ}}{\csc 30^{\circ}}+\frac{\sec 60^{\circ}}{\cot 45^{\circ}}-\frac{5 \sin 90^{\circ}}{2 \cos 0^{\circ}}

=\frac{1}{2}+\frac{2}{1}-\frac{5(1)}{2(1)}

=\frac{1}{2}+2-\frac{5}{2}

=\frac{1+4-5}{2}

=\frac{5-5}{2}

= 0

\frac{\tan 45^{\circ}}{\csc 30^{\circ}}+\frac{\sec 60^{\circ}}{\cot 45^{\circ}}-\frac{5 \sin 90^{\circ}}{2 \cos 0^{\circ}} = 0
