For the acute angle θ with cotθ 1
Webcot(x) = 1/(tan x). If you want to find the cotangent of an angle. Just do 1 divided by the tangent of that angle. Notice, that the words inverse and reciprocal cannot be used … Webcot (θ) = −√3 cot ( θ) = - 3. Take the inverse cotangent of both sides of the equation to extract θ θ from inside the cotangent. θ = arccot(−√3) θ = arccot ( - 3) Simplify the right side. Tap for more steps... θ = 5π 6 θ = 5 π 6. The cotangent function is negative in the second and fourth quadrants. To find the second solution ...
