Solutions to cot(x)= 0 are "3pi/2 +2pik". They are, in fact, where k is any integer. (Which would be the same as .) The tangent and cotangent can be expanded into power series with ... (7)For 0< x <3π√5(π2−8)38, the left inequality in (7) is better than the ... Free Pre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step. 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= [cot(x)] = −csc2(x) d dx. [sec(x)] = sec(x) tan(x) d dx. [csc(x)] = −csc(x) ... = 0. 4. When working with trigonometric functions it is useful to have a ... ... 0, 0.
