Phương trình tan(x) = 1 có nghiệm là các góc mà khi nhân với 4 ta được góc có sin hoặc cos bằng 0 hoặc ±1?

Apr 13, 2023 ... 1 - tan(x) = 1 - sin(x)/cos(x) = (cos(x) - sin(x))/cos(x) = sqrt(2) cos(pi/4 -x)/cos(x) = (cot(x)-1)/cot(x) = (sin(2x)+cos(2x)-1)/sin(2x) = … Sep 14, 2020 ... The equation need to have the variable x in one side. So the equation would be x = tan(x) - 1. It may work and to calculate tan you need to use math.tan(x). Jul 30, 2020 ... tan-1 is known as the inverse (function) of tan, and is also sometimes called arctan. Basically, for values in pre-determined ranges, tan-1 (x) ... Apr 3, 2016 ... It depends on your perspective.
