tan(pi/3)= sqrt(3)
It is 30 which is thirty
tan(61°) = 1.80405 (rounded)
tan(58.5) = 1.63185 (rounded)
-2.2460367739042160541633214384164
tan(135) = -tan(180-135) = -tan(45) = -1
tan(-60 degrees) = - sqrt(3)
tan 2 pi = tan 360º = 0
tan 165/2 = 1.068691
tan(pi/3)= sqrt(3)
1
The exact value of 60 degrees would be 1/2. This is a math problem.
The inexact value of tan 330 is -0.577350, to six significant places. The exact value cannot be represented as a single number because it is a non terminating decimal. To represent it exactly, consider that tan x is sin x over cos x, and that sin 330 is -0.5 and cos 330 is square root of 0.75. As a result, the exact value of tan 330 is -0.5 divided by square root of 0.75.

tan u/2 = sin u/1+cos u
cot(15)=1/tan(15) Let us find tan(15) tan(15)=tan(45-30) tan(a-b) = (tan(a)-tan(b))/(1+tan(a)tan(b)) tan(45-30)= (tan(45)-tan(30))/(1+tan(45)tan(30)) substitute tan(45)=1 and tan(30)=1/√3 into the equation. tan(45-30) = (1- 1/√3) / (1+1/√3) =(√3-1)/(√3+1) The exact value of cot(15) is the reciprocal of the above which is: (√3+1) /(√3-1)
Absolute value of -135 is 135.
