You can put this solution on YOUR website! tan(θ) = cot(30°+5θ) Since tan(θ) = cot(90°-θ) and you only want one value of θ, Replace tan(θ) by cot(90°-θ) cot(90°-θ) = cot(30°+5θ) 90°-θ = 30°+5θ 60° = 6θ 10° = θ [To get all the solutions, since tangent and cotangent have period 180°, add n*180° to 90°-θ cot(90°-θ+n*180°) = cot(30°+5θ) 90°-θ+n*180° = 30°+5θ 60 ...

Find the exact value of cot(390 degrees) Thanks! .. The problem here is to determine the reference angle. Using the unit circle to illustrate this, starting from zero deg, rotate counter-clockwise 360 deg or 2pi radians plus an additional 30 deg, which is the reference angle. The cot of that angle, 30 deg, is the adjacent side/opposite side ...
