Prove that :
`(tan theta)/(sec theta + 1) = (sec theta - 1)/(tan theta)`

(tan theta)/(sec theta+1)+(sec theta+1)/(tan theta)=2cos ec theta

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

Prove that (sec 8theta-1)/(sec 4 theta -1) = (tan 8theta)/(tan 2theta)

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

1+(tan^(2)theta)/((1+sec theta))=sec theta

If : sec theta * tan theta (sectheta + tan theta) + (sec theta - tan theta) = sec^(n) theta + tan^(n) theta, "then" : n = A)1 B)2 C)3 D)4

Prove that (tan theta)/(1-cot theta)+(cot theta)/(1-tan theta)=1+sec theta+tan theta

Prove that: (sec8 theta-1)/(sec4 theta-1)=(tan8 theta)/(tan2 theta)

prove that: (tan theta)/(1-cot theta)+(cot theta)/(1-tan theta)=1+sec theta cosec theta
