Question

If coseca under root 10. Find other 5 trignometric ratios

Answer 1

coseca =✓10

coseca=1/sina

sina =1/✓10

sina =opp side/hyp=1/✓10

so hyp is ✓10 and one side is 1

according to pythogoras theorem,

side^2 +side^2=hyp^2 so

1^2+side^2=✓10^2

1+side^2=10

side^2=10-1=9

side equals 3 which is adj side

Cosa=adj side/hyp =3/✓10

tana equals sina/Cosa

tana=1/3

cota =1/tana=3

seca=1/Cosa=✓10
