Use basic identities to simplify the expression. sin θ cos θ sec θ csc θ

Please help!

hartnn (hartnn):

hint : \(sin x=1/csc x \\ cos x =1/sec x\)

hartnn (hartnn):

so a other huge hint from that \(\sin\:x\:cscx=1 \\ cos\:x\:sec\:x=1\)

OpenStudy (anonymous):

Yes

OpenStudy (anonymous):

But I'm confused as to where I go from there

OpenStudy (anonymous):

How do I simplify all that?

hartnn (hartnn):

sin θ cos θ sec θ csc θ =( sin θ csc θ )(cos θ sec θ) = 1.1 = 1

OpenStudy (anonymous):

Ohhhhh

OpenStudy (anonymous):

Thanks so much

OpenStudy (anonymous):

Great explanation

hartnn (hartnn):

welcome ^_^
