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

If theta=45^(@) then (tan^(2)theta-1)/(sec^(2)theta)=

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

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

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

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

sqrt((1-cos^(2)theta)sec^(2)theta)=tan theta

Prove: ((1+cot^(2)theta)tan theta)/(sec^(2)theta)=cot theta

Prove that: (1+sec 2theta)(1+sec2^(2)theta)(1+sec2^(3)theta)...... xx )(1+sec2^(n)theta) = tan2^(n)theta* cot theta

(sec^(2)theta-1)/(tan^(2)theta)=?
