Dec 21, 2005 ... arcsech(x) = ln((1 + sqrt(1 - x^2)) / x). cot x = 1 / tan x. coth x = cosh x / sinh x. csc x = 1 / sin x. csch x = 1 / sinh x. log(x,y) = log10( ... cosecant(x) = csc(x) = 1/sin(x) = sin(x)-1. secant(x) = sec(x) = 1/cos(x) = cos(x)-1. cotangent(x) = cot(x) = 1/tan(x) = tan(x)-1. For example: Solve for the ... ... 13x3> fixed_point_method('1/tan(x)-1/x+x',4.5,1000,10^-4). Took 2 iterations ...

Correct answer: (2/x) + ... sin(x)/cos(x) is the same as tan(x). Therefore, the answer is: cos(x)ln ... Feb 10, 2020 ...
