Question

sec²60°+cosec²30°= ​

Answer 1

Answer:

sec²60°+cosec²30°= 4+4=8

sec60°= 2 and cosec30°=2

Answer 2

$Value \: of \: sec^{2} 60\degree + Cosec^{2} 30\degree$

$= sec^{2} 60\degree + Cosec^{2} (90-60)\degree$

$= sec^{2} 60\degree + sec^{2} 60\degree$

$= 2sec^{2} 60\degree$

$= 2 \times 2^{2}$

$= 2 \times 4$

$= 8$

Therefore.,

$\red{Value \: of \: sec^{2} 60\degree + Cosec^{2} 30\degree}\green {= 8}$
