Question

if cos B= 1/3 find the other trignometric ratio

Answer 1

cosx=1/3

u can do this in two ways

M1:

just draw a triangle and solve it

M2:

use the trigonometric equations

i will do it with the 2nd one

sinx=√(1-cos²x)

=√(1-1/9)

=2√2/3

tanx=sinx/cosx

=2√2/3/1/3

=2√2

others are just reverse of the given three

secx=3

cosecx=3/2√2

cotx=1/2√2
