" i) "(sin theta+sec theta)^(2)+(cos theta+cosec6)^(2)=(1+sech alpha

Prove the following identity : (sin theta+ sec theta)^2 +(cos theta+ cosec theta)^2= (1+ sec theta cosec theta)^2 .

Prove that : (sin theta + sec theta) ^(2) + (cos theta + cosec theta) ^(2) = (1 + sec theta cosec theta) ^(2).

(sin theta+sec theta)^(2)+(cos theta+csc theta)^(2)=(1+cos ec theta sec theta)^(2)

Prove that (sin theta + "cosec" theta)^(2)+(cos theta + sec theta)^(2)=(7+ tan^(2) theta + cot^(2) theta).

(sin theta)/(cosec theta)+(cos theta)/(sec theta)=1

The minimum value of (sin theta+csc theta)^(2)+(cos theta+sec theta)^(2)=

( sin theta + " cosec " theta )^(2) + ( cos theta + sec theta )^(2)=

Prove the following identity : (sin theta+ cos theta) (sec theta+ cosec theta) =2+ sec theta cosec theta .

(cos theta cosec theta-sin theta sec theta)/(cos theta+sin theta)=cosec theta-sec theta

Prove that (1+ cot theta + tan theta ) ( sin theta - cos theta) = (sec theta )/(cosec^(2) theta) - (cosec theta)/(sec^(2)theta) .
