Simplify please and show steps:<br><br> Sec (x) tan (x) csc (x) cot (x) sin (x) cos (x)
Airida [17]

Answer:

<h2>The answer is 1</h2>

Step-by-step explanation:

First of all transform the expression using trigonometric identities

That's

\sec(x)  =  \frac{1}{ \cos(x) }

\csc(x )   =  \frac{1}{ \sin(x) }

\cot(x)  =  \frac{1}{ \tan(x) }

So we have

\frac{1}{ \cos(x) }  \times  \tan(x)  \times  \frac{1}{ \sin(x) }  \times  \frac{1}{ \tan(x) }  \times  \sin(x)  \times  \cos(x)

Reduce the expression with tan x

We have

\frac{1}{ \cos(x) }   \times \cos(x)  \times  \frac{1}{ \sin(x) }  \times  \sin(x)

Reduce the expression with cos x

That's

1 \times  \frac{1}{ \sin(x) }  \times  \sin(x)

Reduce the expression with sin x

We have

1 \times 1

We have the final answer as

<h3>1</h3>

Hope this helps you

A student claimed 7 and -7 are the two cube roots of 343 . Do you agree or disagree ? Explain .
dmitriy555 [2]
I disagree. Only 7 is a cube root of 343 (7 x 7 x 7) because -7 is a cube root of -343 (-7 x -7 x -7)
