Question

if cos B is equals to 1 by 3 then find the other 5 trigonometric ratios

Answer 1

Sinb= -2 root2/3
Tan b= -2 root 2
Cot b= -1/2 root 2
Cosec b = -3 /2 root 2
Sec b = + 3.

Answer 2

cos B=c/a=1/3
sin B=b/a
b=$2 \sqrt{2}$
sin B=$2 \sqrt{2}$/3
cosec B=3/$2 \sqrt{2}$
sec B=3/1
tan B=$2 \sqrt{2}$/1
cot B=1/$2 \sqrt{2}$
