If sec thita -tan thita =xShow that sec thita +tan thita =1/x

1.	If sec thita -tan thita =xShow that sec thita +tan thita =1/x
Answer» Multiply (sec theta - tan theta) with (sec theta + tan theta)/(sec theta + tan theta). This will give you x=reciprocal of(sec theta + tan theta). Thus 1/x= sec theta + tan theta
