" 2."sec theta(1-sin theta)(sec theta+tan theta)=1

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 ?

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

Prove that : (sec theta-tan theta)/(sec theta+tan theta)= 1-2 sec theta tan theta+ 2 tan^2 theta .

Value of sec theta(1-sin theta)(sin theta+tan theta) is

Value of sec theta(1-sin theta)(sin theta+tan theta) is

Value of sec theta(1-sin theta)(sin theta+tan theta) is

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

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

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

Prove that (sec theta-tan theta+1)/(sec theta+tan theta+1)=(1-sin theta)/(costheta) .
