" Example "14:" Prove that "(cot A-cos A)/(cot A+cos A)=(cosec A-1)/(cosec A+1)

Prove that (cot A - cos A)/(cot A + cos A) = (cosec A -1)/(cosecA+1) .

Show that (cot A - cos A)/(cot A + cos A) = ( cosec A - 1)/(1 + cosec A)

(cosec A)/(cot A+tan A)=cos A

cosec A- 2cot 2A cos A=

Prove the following : (cot A - cos A)/(cot A + cos A) = (cosec A -1)/(cosec A + 1) .

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

cosec A -2 cot 2A cos A=

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

Prove that : (1 + cos A)/(1 - cos A) = (cosec A + cot A)^(2)

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