Question

if cosec tetha is 3x and cot tetha is 3/x the find the value of 3(x²-1/x²)​

Answer 1

Answer:

If 3x = cosecθ and x3 = cotθ then find 3(x2+x 21). Share. Study later. Answer. 3x=cscθ and x3=cotθ. ⇒x=3cscθ and x1=3cotθ.

Answer 2

Answer:

1/3

Step-by-step explanation:

$3( {x}^{2} - \frac{1}{ {x}^{2} } ) \\ \frac{1 }{3} (9{x}^{2} - \frac{9}{ {x}^{2} } ) \\ \frac{1}{3} ( {(3x)}^{2} - \frac{ {3}^{2} }{ {x}^{2} } ) \\ \frac{1}{3} ( { \csc( \alpha ) }^{2} - { \cot( \alpha ) }^{2} ) \\ \frac{1}{3} \times 1 \\ = \frac{1}{3}$
