`cosec^4 theta-cot^4 theta=cosec^2theta+cot^2 theta`

(1)/(cosec theta+cot theta)=cosec theta-cot theta

Prove that cot^4 theta+ cot^2 theta= cosec^4 theta-cosec^2 theta

x=a cosec theta+b cot theta, y=a cosec theta-b cot theta . Then, ((x+y)/(a))^(2)-((x-y)/(b))^(2)=4

int(cosec theta-cot theta)/(cosectheta+ cot theta)d theta=

Prove that: ("cosec" theta + cot theta)/("cosec" theta - cot theta) = ("cosec" theta + cot theta )^(2) = 1 + 2 cot^(2) theta + 2 "cosec" theta cot theta .

The value of sqrt((cosec theta-cot theta)/(cosec theta+cot theta)) div (sin theta)/(1+cos theta) is equal to: sqrt((cosec theta-cot theta)/(cosec theta+cot theta)) div (sin theta)/(1+cos theta) का मान निम्नलिखित में से किसक बराबर है?

If cot theta= sqrt7 , then the value of (cosec^2 theta-sec^2 theta)/(cosec^2 theta+sec^2 theta) is: यदि cot theta= sqrt7 , है, तो (cosec^2 theta-sec^2 theta)/(cosec^2 theta+sec^2 theta) का मान क्या होगा ?

If 5 costheta = 3 , then ( "cosec "theta+cot theta)/(" cosec " theta- cot theta) is equal to

cosec^(2)theta-cot^(2)theta-1
