Question

tan1305+sec2400 evaluate​

Answer 1

$\red{ Value \: of \: tan 1305 + Sec 2400 }$

$= tan ( 4 \times 360 - 135 ) + Sec ( 7\times 360 +120)$

$= - tan (135) + Sec (120)$

$= - tan ( 90 + 45) + Sec( 90 + 30 )$

$= - ( - cot \:45 ) + ( - Cosec \: 30 )$

$= cot 45\degree - Cosec 30$

$= 1 - 2$

$= -1$

Therefore.,

$\red{ Value \: of \: tan 1305 + Sec 2400 }\green { = -1 }$
