Question

Use basic identities to simplify the expression sinx cosx secx cscx

Answer 1

opp = opposite
adj = adjacent
hyp = hypotenuse

\[sin x = \frac{opp}{hyp}\]\[cos x = \frac{adj}{hyp}\]\[secx = \frac{hyp}{adj}\]\[cscx = \frac{hyp}{opp}\]
so you are asking to simplify this really:
\[ \frac{opp}{hyp} \times \frac{adj}{hyp} \times \frac{hyp}{adj} \times \frac{hyp}{opp}\]

Answer 2

since: (sin x)* (cosec x)=1 and (cos x)* (sec x==1 then your expression ie equal to ?

Answer 3

sec = 1/cos and csc = 1/sin

so you have, with a little rearranging

\[\sin \times \frac{1}{\sin} \times \cos \times \frac{1}{\cos} = ? \]

you need to find the value of ?

Answer 4

\[\sin = \frac{ 1 }{ \csc }\]
\[\cos = \frac{ 1 }{ \sec }\]
\[\tan = \frac{ \sin }{ \cos }\]
you should have to know this for trig
\[\sec = \frac{ 1 }{ \cos }\]
\[\csc = \frac{ 1 }{ \sin }\]
\[\cot = \frac{\cos }{ \sin}\]

Answer 5

Answers most be one of this:
sec^2x
csc^2x
1
tan^2x

Answer 6

okay so you have t o solve campbell_st<=== read what he did

Answer 7

you can change secx
and cscx
like cambell_st did
cscx =1/sin so change csc to 1/sin

Answer 8

Ok thanks, I get it now, the final answer is 1. Thanks once again!!!

Answer 9

yes right :)

Answer 10

my pleasure :)
