write in terms of sin, cos or tan
then use the double angle formulae.
I.e. cosec(x)=1/sin(x)
=1/[2sin(x)cos(x)]

The trig identaty of cot(x) is cos(x)/sin(x) so then if we want to evaluate cot (68) deg. we just plug into the identady. so cos(68)/sin(68)=.404
Cotan(theta) is the reciprocal of the tan(theta). So, cot(theta) = 1/2.
When you subtract theta from 180 ( if theta is between 90 degrees and 180 degrees) you will get the reference angle of theta; the results of sine theta and sine of its reference angle will be the same and only the sign will be different depends on which quadrant the angle is located. Ex. 150 degrees' reference angle will be 30 degrees (180-150) sin150=1/2 (2nd quadrant); sin30=1/2 (1st quadrant) 1st quadrant: all trig functions are positive 2nd: sine and csc are positive 3rd: tangent and cot are positive 4th: cosine and secant are positive
Every multiple of 180 degrees, beginning with zero.
cot 15 = cot(45 - 30) = cot45.cot30 - 1 / cot45 + cot 30
The cotangent of a 29-degree angle, denoted as cot(29°), is the reciprocal of the tangent of that angle. It can be calculated using the formula cot(θ) = 1/tan(θ). For practical purposes, cot(29°) is approximately 1.962. This value can be found using a scientific calculator or trigonometric tables.

The cotangent of an angle, denoted as cot(θ), is defined as the ratio of the cosine to the sine of that angle: cot(θ) = cos(θ) / sin(θ). For cot(0), since cos(0) = 1 and sin(0) = 0, the expression becomes cot(0) = 1 / 0. Therefore, cot(0) is undefined because division by zero is not possible.
cot 32° = 1/(tan 32°) = 1/(0.6249) = 1.6003
For an angle, ?, the cotangent (or cot) of the angle is given bycot ? = 1/tan ?If ?=65
a 30-degree angle .
cot(69) = 0.3839, approx.
cot(32 deg) = 1.6003, approx.
the cotangent of a 50 degree angle is -3.678 This is in Radians. The cotangent of a 50 degree angle is .8391 (rounded) degrees.
The trig identaty of cot(x) is cos(x)/sin(x) so then if we want to evaluate cot (68) deg. we just plug into the identady. so cos(68)/sin(68)=.404
