` ( sin A + cosec A ) ^ 2 + ( cos A + sec A) ^ 2 = 7 + tan ^ 2 A + cot ^ 2 A `

(1 + cot A — cosec A) (1 + tan A + sec A) = 2 .

( cosec A - sin A ) (sec A - cos A ) = ( 1 ) /( tan A + cot A )

Prove that : (cosec A - sin A) (sec A - cos A) sec^(2) A = tan A

sin A (1 + tan A) + cos A (1 + cot A) = sec A + cosec A .

(cosec A - sin A)^2 + (sec A - cos A)^2 - (cot A - tan A)^2 is equal to

If (sin alpha + "cosec" alpha )^(2) + ( cos alpha + sec alpha )^(2)=k+ tan^(2) alpha + cot^(2) alpha then k=

If (sin prop + cosec prop)^2 +(cos prop + sec prop)^3= k +tan^2 prop + cot^2 prop, then the value of k=___.

Prove that (cosec A - sin A ) (sec A -cos A) = ( 1)/( tan A +cot A)

Prove that (cosec A - sin A ) (sec A -cos A) = ( 1)/( tan A +cot A)
