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 ...

Question 586707: What is the exact value of cot - 30? Answer by ad_alta(240) (Show Source):

2015年10月28日 · Find value of cot (930) Ans: sqrt3 On the trig unit circle, cot (930) = cot (-150 + 3(360)) = cot (-150) = cot 30^@ = sqrt3 Trigonometry Science

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 ...

Rewrite 75 as 45+30 (note: 45 and 30 are known angles on the unit circle) Use the identity Evaluate to get 1. Evaluate to get (use the unit circle) Multiply Combine the fractions. Divide the inner fractions (by multiplying by the reciprocal of the second inner fraction) Cancel out like terms. Simplify Flip the fraction.

2018年6月10日 · amplitude: 1 period: 2pi vertical phase shift: 0 horizontal phase shift: right 30 degrees or pi/6 in radians cot is not being multiplied by anything therefore amplitude is 1. period of tangent and cotangent with no stretch is always 2pi. nothing is being added outside of the inner function so there is no vertical shift, but there is subtraction inside the inner function shifting it …
