\[\frac{ 1 }{ 1+\sin \theta }+\frac{ 1 }{ 1\sin \theta }\] The LCD (least common multiple of the denominators) is (1 + sin θ)(1 − sin θ). Hence \[\frac{ 1 }{ 1+\sin \theta }+\frac{ 1 }{ 1\sin \theta }\] \[=\frac{ 1\sin \theta }{(1+\sin \theta)(1\sin \theta) }+\frac{ 1+\sin \theta }{ (1+\sin \theta)(1\sin \theta) }\] \[=\frac{ 1\sin \theta +1+\sin \theta }{ (1+\sin \theta)(1\sin \theta) }\] \[=\frac{ 2 }{ 1\sin ^{2}\theta }\] \[=\frac{ 2 }{ \cos ^{2}\theta }\] \[=2\sec ^{2}\theta \] I hope that helps!
