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

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
The TI-83 does not have the cot button, however, if you type 1/tan( then this will work the same as the cot since cot=1/tan. The other way to do this is to type (cos(x))/(sin(x)) where x is the angle you're looking for. This works because cot=cos/sin
