In a right triangle, where the angle "x" is adjacent to the hypotenuse, the tangent of that angle would be the length of the opposite side divided by the length of the adjacent side (not the hypotenuse).
For instance, consider a right triangle with the following side lengths:
A = 3
B = 4
C = 5
B is the hypotenuse. The tangent of the angle between sides A and C would be B/A, or 4/3. The tangent of the angle between sides B and C would be B/A, or 3/4.
This is often taught with the memorisation acronym "SOHCAHTOA":
(S)ine = (O)pposite / (H)ypotenuse
(C)osine = (A)djacent / (H)ypotenuse
(T)angent = (O)pposite / (A)djacent

The value of (\tan(22.5^\circ)) can be calculated using the half-angle formula for tangent: [ \tan\left(\frac{x}{2}\right) = \frac{1 - \cos(x)}{\sin(x)} ] For (x = 45^\circ), this simplifies to: [ \tan(22.5^\circ) = \sqrt{2} - 1 \approx 0.4142 ] Thus, (\tan(22.5^\circ)) is approximately 0.4142.
The definition of tan(x) = sin(x)/cos(x). By this property, cos(x)tan(x) = sin(x).
The derivative of ( \tan x ) with respect to ( x ) is ( \sec^2 x ). This can be derived using the quotient rule, since ( \tan x = \frac{\sin x}{\cos x} ), or recognized as a standard derivative. Thus, when differentiating ( \tan x ), you get ( \frac{d}{dx}(\tan x) = \sec^2 x ).
tan (A-B) + tan (B-C) + tan (C-A)=0 tan (A-B) + tan (B-C) - tan (A-C)=0 tan (A-B) + tan (B-C) = tan (A-C) (A-B) + (B-C) = A-C So we can solve tan (A-B) + tan (B-C) = tan (A-C) by first solving tan x + tan y = tan (x+y) and then substituting x = A-B and y = B-C. tan (x+y) = (tan x + tan y)/(1 - tan x tan y) So tan x + tan y = (tan x + tan y)/(1 - tan x tan y) (tan x + tan y)tan x tan y = 0 So, tan x = 0 or tan y = 0 or tan x = - tan y tan(A-B) = 0 or tan(B-C) = 0 or tan(A-B) = - tan(B-C) tan(A-B) = 0 or tan(B-C) = 0 or tan(A-B) = tan(C-B) A, B and C are all angles of a triangle, so are all in the range (0, pi). So A-B and B-C are in the range (- pi, pi). At this point I sketched a graph of y = tan x (- pi < x < pi) By inspection I can see that: A-B = 0 or B-C = 0 or A-B = C-B or A-B = C-B +/- pi A = B or B = C or A = C or A = C +/- pi But A and C are both in the range (0, pi) so A = C +/- pi has no solution So A = B or B = C or A = C A triangle ABC has the property that tan (A-B) + tan (B-C) + tan (C-A)=0 if and only if it is isosceles (or equilateral).
The formula for (\tan(2x)) is given by the double angle identity: [ \tan(2x) = \frac{2\tan(x)}{1 - \tan^2(x)} ] This formula allows you to express the tangent of double an angle in terms of the tangent of the original angle (x).
To find the direction of a vector, you can use the formula: θ = tan^(-1) (y/x), where θ is the angle of the vector with the positive x-axis, and (x, y) are the components of the vector along the x and y axes, respectively.

1 (sec x)(sin x /tan x = (1/cos x)(sin x)/tan x = (sin x/cos x)/tan x) = tan x/tan x = 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.
y = 2*tan(2x) is an equation in two variable. There can be no answer. While x can be made the subject of the formula, that is not an *answer*.
The value of (\tan(22.5^\circ)) can be calculated using the half-angle formula for tangent: [ \tan\left(\frac{x}{2}\right) = \frac{1 - \cos(x)}{\sin(x)} ] For (x = 45^\circ), this simplifies to: [ \tan(22.5^\circ) = \sqrt{2} - 1 \approx 0.4142 ] Thus, (\tan(22.5^\circ)) is approximately 0.4142.
tan(-x) = -tan(x)
No. Tan(x)=Sin(x)/Cos(x) Sin(x)Tan(x)=Sin2(x)/Cos(x) Cos(x)Tan(x)=Sin(x)
There is not much that can be done by way of simplification. Suppose arccot(y) = tan(x) then y = cot[tan(x)] = 1/tan(tan(x)) Now cot is NOT the inverse of tan, but its reciprocal. So the expression in the first of above equation cannot be simplified further. Similarly tan[tan(x)] is NOT tan(x)*tan(x) = tan2(x)
tan x
tan(x)*csc(x) = sec(x)
