Question

evaluate the following without calculator tan(7pi/6)

Answer 1

ok so what is Pi/6 radian in degrees?

Answer 2

double angle formula

Answer 3

210 degrees

Answer 4

thats from radians to degrees

Answer 5

yeah @micahcarr76 u can use tan(180+x) = tan x which will be positive in quad 3

Answer 6

we know that tangent is sin(x)/cos(x) we know that 7pi/6 will take us into the 3rd quadrent where both cos and sin are negative so evaluate sin(pi/6)and cos(pi/6) make and divide them which will give you a positive value for your tangent
