Question

find the value of cosec*2 60° - tan*2 30° [hint. *2 means square] ?

Answer 1

Answer:

value of cosec and tan are taken from the table of trigonometric ratios....

Answer 2

Answer:

${ \csc(60) }^{2} - \ { \tan(30) }^{2} \\ = ( \frac{2}{ \sqrt{3} }) {}^{2} - ( \frac{1}{ \sqrt{3} } ) {}^{2}$

$= \frac{4}{3} - \frac{1}{3}$

=$\frac{3}{3 } = 1$

so your answer is 1
