Question

Sec/tan-1/tan=cosec-cot

Answer 1

L.H.S

$\frac{sec}{tan} - \frac{1}{ \tan} \\ \\ \frac{1}{cos} \times \frac{ \cos }{ \sin} - \frac{1}{ \frac{sin}{cos} } \\ \\ = > \frac{1}{sin} - \frac{cos}{sin} \\ \\ = > cosec - cot$
L.H.S=R.H.S ( proved)

hope it will help you ☺️

Answer 2

sec/tan- cot. ( 1/tan = cot )
1/cos/sin/cos - cot. (sec = 1/cos ; tan = sin/cos )
1/cos ×cos/sin - cot
1/sin - cot
cosec - cot. ( 1/ sin = cosec )
