Best ResponseYou've already chosen the best response.3\[\frac{\cot x\tan x}{\sin x+\cos x}=\csc x\sec x\]

Best ResponseYou've already chosen the best response.3Do I have the problem stated correctly?

Best ResponseYou've already chosen the best response.0would I have to replace cot(x) with cos(x)/sin(x)

Best ResponseYou've already chosen the best response.0and tan(x) with sin(x)/cos(x)

Best ResponseYou've already chosen the best response.3\[(\frac{\frac{\cos x}{\sin x}\frac{\sin x}{\cos x}}{\sin x+\cos x})\times \frac{\sin x \cos x}{\sin x \cos x}=\frac{\cos ^2x\sin ^2x}{\sin x \cos x(\sin x+\cos x)}\]

Best ResponseYou've already chosen the best response.0sadly no? can you explain how I can simplify it more please?

Best ResponseYou've already chosen the best response.3Factor the numerator and then the cosx + sinx will cancel.

Best ResponseYou've already chosen the best response.0how would I factor it though? I'm sorry I am new to trig.

Best ResponseYou've already chosen the best response.3Can you factor this: \[a^2b^2\]

Diana0920

Best ResponseYou've already chosen the best response.0I don't think you can because it doesn't have the same coefficient

Best ResponseYou've already chosen the best response.3\[\cos ^2x\sin ^2x=(\cos x\sin x)(\cos x+\sin x)\]

Best ResponseYou've already chosen the best response.0oh okay that makes sense. so would it be cossin(cos+sin)

Diana0920

Best ResponseYou've already chosen the best response.0then that would cancel with the denominator correct?

Mertsj

Best ResponseYou've already chosen the best response.3Yes. sinx + cosx will cancel

Diana0920

Best ResponseYou've already chosen the best response.0which will leave 1/sin(x)+cos(x)

Best ResponseYou've already chosen the best response.0using the reciprocal identities this will equal csc(x)sec(x) ?

Diana0920

Best ResponseYou've already chosen the best response.0cos(x)sin(x)/sin(x)+cos(x0

Diana0920

Best ResponseYou've already chosen the best response.0this is where I would use the reciprocal identities?

Diana0920

Best ResponseYou've already chosen the best response.0the cos(x) cancel and the sin(x) cancels?

Diana0920

Best ResponseYou've already chosen the best response.0yay!!!! the cancel and its one,which now you are left with the csc(x) and sec(x) reciprocal identities!! Thank you!! the key idea here that I need to work on was the factoring
