Prove the identity 2csc2x=csc^2xtanz
Verizon [17]

Step-by-step explanation:

Consider the LHS, after the 5th step, consider the RHS

2 \csc(2x)  =  \csc {}^{2} (x)  \tan(x)

2 \frac{1}{ \sin(2x) }  =  \csc {}^{2} (x)  \tan(x)

2  \times \frac{1}{2 \sin(x)  \cos(x) }  =  \csc {}^{2} (x)  \tan(x)

\frac{1}{ \sin(x) \cos(x)  }  =   \csc {}^{2} (x)  \tan(x)

\csc(x)  \sec(x)  =  \csc {}^{2} (x)  \tan(x)

Consider the RHS

\csc(x)  \sec(x)  =( 1 +  \cot {}^{2} (x) ( \tan(x))

\csc(x)  \sec(x)  =  \tan(x)  +  \cot(x)

\csc(x)  \sec(x)  =  \frac{ \sin(x) }{ \cos(x) }  +  \frac{ \cos(x) }{ \sin(x) }

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

\csc(x)  \sec(x)  =  \csc(x)  \sec(x)

Answer:

Read below

Step-by-step explanation:

a) \frac{-7}{9} = -\frac{7}{9}  = \frac{7}{-9}

b) \frac{4}{3} =\frac{-4}{-3} (The reason both numerator and denominator can both be negative is because the negative cancel each other out and still simplify to \frac{4}{3})

<u>√3</u>

x is the length of the third side

x²+1² = 2² { Pythagorean Theorem}

x²+1 = 4 {Simplify}

x²=3 {Subtract 1 from each side}

x=√3 {Take the square root of each side}

The Length of the third side is √3
