In this video, we will learn to find the principal and general solutions to the equation “cot x = 1”. The proof the identity cot(pi + x) ... Jul 16, 2015 ... tan x + cot x = sinx/cosx + cosx/sinx = [get a common denominator] [sin^2x + cos^2x] / [sinx*cosx] = 1/ [sin x * cosx [A] Yes, it matters. The graph of the function y = cot(x) should be reflected about the x-axis before it is translated 1 unit down. Jan 27, 2013 ... Let's make the "right side" of the equation look like the left: (1-cot(X))/(1+cot(X)) since cot(x) = 1/tan(x) we can rewrite as: (1-1/tan(x))/ Feb 18, 2022 ...
