`(cosec A. cosecB+cotA . cotB)^2-(cosec A. cotB + cosecB. cot A)^2` is

Prove that : cosec A- cot A =(1)/(cosecA+cotA)

Prove that : cosec A- cot A =(1)/(cosecA+cotA)

If cosec A +cotA= 5/2, then tan A is

The value of (cosecA+cotA+1) (cosec A-cot A+1) -2 cosec A is:

If A+B+C= pi and cosA cosecB cosecC + cosB cosecA cosecC + cosC cosecA cosecB = s and 1+ cot 81^@ + cot 54^@ + cot 81^@ cot54^@ = p, then

Prove that : cot (A-B)= (cotA cot B+1)/(cotB -cotA) .

Prove that cotA-cosec2A=cot2A

Prove that- cot(A+B)=(cotA.cotB-1)/(cotA+cotB)

Prove that : cot (A+B)= (cotA cot B-1)/(cotB + cotA) .

prove that (cosec theta + cot theta)/(cosec theta- cot theta) = (cosec theta +cot theta)^2
