Question

Find the values of all trigonometric functions of 7π/6​

Answer 1

Answer:

Hello ✌️✌️✌️✌️✌️

Step-by-step explanation:

sin(7π/6) = sin(π+π/6) = -sin(π/6) = -1/2

cos(7π/6) = cos(π+π/6) = -cos(π/6) = -√3/2

tan(7π/6) = sin(7π/6)/cos(7π/6) = (-1/2)/(-√3/2) = 1/√3

cot(7π/6) = 1/tan(7π/6) = √3

sec(7π/6) = 1/cos(7π/6) = -2/√3

cosec(7π/6) = 1/sin(7π/6) = -2

Answer 2

Answer:

sin7π/6= -1/2

cos7π/6= -root3/2

tan7π/6= 1/root3
