Question

sin+cosec=3 find sin4 +1/sin2

Answer 1

0.539560235 is your answer

Answer 2

sin + cosec = 3--------1 equation

sin = 1/cosec ( they are reciprocals )

from 1

sin = 3 - cosec
1/cosec = 3-cosec
cosec ( 3 - cosec ) = 1---------2 equation

sin^4 + 1/sin^2

==> ((sin^4+2)+1)/sin^2 [ by taking LCM]
==> (sin^6 +1)/sin^2

Hey my friend this is the answer...
if u want it in terms of cosec just take sin as 1/cosec in the answer

thanks hope it helps
