" 2."(cos theta)/(1+sin theta)+(cos theta)/(1-sin theta)=hat 2sec theta

Prove : (cos theta)/(1+sin theta) + (cos theta)/(1-sin theta)= 2 sec theta

Prove :(cos theta)/(1+sin theta)+(cos theta)/(1-sin theta)=2sec theta

Prove the following identities: (cos theta)/(1-sin theta)+(cos theta)/(1+sin theta)=2sec theta

(cos theta)/(1+sin theta)+(1+sin theta)/(cos theta)=2sec theta

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

" 4."(sin theta)/(1+cos theta)+(1+cos theta)/(sin theta)=(2)/(sin theta)

Prove that (costheta)/(1-sin theta)+(1-sin theta)/(cos theta)=2sec theta .

Show that (1 + sin theta)/ cos theta + cos theta / (1 + sin theta) = 2 sec theta

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

(1+ sin theta - cos theta )/( 1+ sin theta + cos theta ) + (1+ sin theta + cos theta )/( 1+ sin theta - cos theta ) =
