Step One is going to be getting everything in terms of the same function, namely tangent! As cot(x) = 1/tan(x) we have 3%2Atan%28x%29+-+1%2F%28tan%28x%29%29= Detailed Solution: cot x = 0 ⇒ cot x = cot π 2 ⇒ x = π 2 is the principal solution. Watch 3-min video & get full concept clarity. Intervals with а constant sign: cotx>0 (cotangent function takes positive values) for all x on the interval (0; π/2), and on all intervals ... Dec 16, 2014 ... (0,0) local mai.
