With a plastic impact, the coeffecient of restitution is 0. With an elastic impact, the coeffecient of restitution is 0<e<1. With an inelastic impact, the coeffecient of restitution is 1.
The numerical coeffecient of -x is -1.
The numerical coeffecient of -x is -1.

cot(15)=1/tan(15) Let us find tan(15) tan(15)=tan(45-30) tan(a-b) = (tan(a)-tan(b))/(1+tan(a)tan(b)) tan(45-30)= (tan(45)-tan(30))/(1+tan(45)tan(30)) substitute tan(45)=1 and tan(30)=1/√3 into the equation. tan(45-30) = (1- 1/√3) / (1+1/√3) =(√3-1)/(√3+1) The exact value of cot(15) is the reciprocal of the above which is: (√3+1) /(√3-1)
tan (pi) / 1 is zero. tan (pi / 1) is zero.
Is the '1' one degree , or one radian or, Tan(angle) = 1. You need to clarify. However, Tan(1 degree) = 0.017455... Tan( 1 radian) = 1.55740.... Tan(angle) = 1 Angle = Tan^(-1) 1 = 45 degrees. = pi/4 radians.
If the angles are measured in degrees or gradians, then: tan 3 > tan 2 > tan 1 If the angles are measured in radians, then: tan 1 > tan 3 > tan 2.
tan 45 = 1

tan(135) = -tan(180-135) = -tan(45) = -1
cot2x-tan2x=(cot x -tan x)(cot x + tan x) =0 so either cot x - tan x = 0 or cot x + tan x =0 1) cot x = tan x => 1 / tan x = tan x => tan2x = 1 => tan x = 1 ou tan x = -1 x = pi/4 or x = -pi /4 2) cot x + tan x =0 => 1 / tan x = -tan x => tan2x = -1 if you know about complex number then infinity is the solution to this equation, if not there's no solution in real numbers.
