If `A(theta)=[(1, than theta),(-tan, theta=1)]` and `AB=l`, then `(sec^(2)theta)B` is equal to

If tan^2 theta =(1-e^2) , then sec theta+tan^3 theta "cosec" theta is equal to

For 0 prec theta prec 90 , if (sec theta( 1- sin theta)(sec theta+tan theta))/(sec theta-tan theta)^2=(1+k)/(1-k) , then k is is equal to : 0 prec theta prec 90 के लिए , यदि (sec theta( 1- sin theta)(sec theta+tan theta))/(sec theta-tan theta)^2=(1+k)/(1-k) है, तो k का मान किसके बराबर है ?

( tan theta)/( sec theta -1)-(tan theta )/( sec theta + 1)=

(cot theta)/((1-sin theta) (sec theta + tan theta)) is equal to:

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

(cot theta)/((1-sin theta)(sec theta + tan theta)) is equal to :

( sec theta + tan theta -1)/( tan theta - sec theta +1)

(1+sec theta - tan theta)/(1+sec theta + tan theta)=

(1+sec theta-tan theta)/(1+sec theta+tan theta)=
