(1)/(1+sin A)+(1)/(1-sin A)

Prove (1)/(1+sin theta)+(1)/(1-sin theta)=2sec^(2)theta

Prove the following trigonometric identities: cos^(2)theta+(1)/(1+cot^(2)theta)=1 (ii) (1)/(1+sin theta)+(1)/(1-sin theta)=2sec^(2)theta

(1)/(1+sin theta ) +(1)/(1-sin theta) = ?

(1)/(1+ sin theta) + (1)/(1- sin theta)= ________

(1)/(1-sin theta)-(1)/(1+sin theta)=(2tan theta)/(cos theta)

(1)/(1-sin theta)-(1)/(1+sin theta)=2sec theta*tan theta

Prove that (1)/(1-sin theta) +(1)/(1+sin theta) = 2sec^2 theta

Show that cos theta((1)/(1-sin theta)-(1)/(1+sin theta)) can be written in the form k tan theta and find the value of ^( k.)

Show that (cosec A - 1)/(cosec A + 1) = (1 - sin A)/(1 + sin A)

If (1/(1-sin theta) +1/(1+sin theta)) = 4sec theta , 0^circ lt theta lt 90^circ then the value of (3cot theta + cosec theta) is: यदि (1/(1-sin theta) +1/(1+sin theta)) = 4sec theta , 0^circ lt theta lt 90^circ है, तो (3cot theta + cosec theta) का मान हैः
