`(cos theta )/( sec theta + tan theta ) + ( cos theta )/( sec theta - tan theta ) = `

If sec theta + tan theta = k, cos theta =

Prove that (sin theta + cos theta )( cosec theta - sec theta ) = cosec theta. Sec theta -2 tan theta

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

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

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

If 4 cos theta - sec theta = 4 tan theta then theta =

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

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

Prove that (sin theta -cos theta+1 )/( sin theta + cos theta -1) =(1)/( sec theta -tan theta ) [use the identity sec ^(2) theta =1 +tan ^(2) theta ]
