Question

please solve questions 7 part 1,2(a,b,c)​

Answer 1

7) Cosec 0= 41/40

sin 0=1/cosec 0

sin 0=40/41

by using identity,

sin square 0 + cos square 0=1

(40/41) square + cos square 0=1

cos square 0=1 - 1600/ 1681

cos square = 1681 - 1600/1681

cos square 0= 81/1681

cos= root 81 / 1681

cos 0= 9/41

cos=1/sec 0

sec 0=1/cos 0

sec 0=1/9/41

sec 0=41/9
