Ctg Minus 0.84 Radians
If you want to know what is ctg -0.84 radians in terms of trigonometry, then navigate straight to the explanations in the next paragraph; what’s ahead in this section is the value of ctg -0.84:
ctg -0.84 = -0.89635
ctg -0.84 radians = -0.89635
The ctg of -0.84 radians is -0.89635, the same as ctg of -0.84 radians in degrees. To change -0.84 radians to degrees multiply -0.84 by 180° / $\pi$ = -48.12845°. Ctg -0.84 = ctg -48.12845 degrees.
Our results of ctg-0.84 have been rounded to five decimal places. If you want cotangent -0.84 with higher accuracy, then use the calculator below; our tool displays ten decimal places.
To calculate ctg -0.84 radians insert the angle -0.84 in the field labelled rad, but if you want to calculate ctg -0.84 in degrees, then you have to press the swap unit button first.
Calculate ctg [radians]
The identities of cotangent -0.84 are as follows:
= tg (π/2 + 0.84) = tg 2.4107963267949
-ctg-0.84
= ctg 0.84 = -ctg -0.84
= tg (π/2 – 0.84) = tg 0.730796326794897
= ctg (π + 0.84) = ctg 3.98159265358979
There are more formulas for the double angle (2 × -0.84), half angle ((-0.84/2)) as well as the sum, difference and products of two angles such as -0.84 and β.

In terms of the other five trigonometric functions, ctg of -0.84 =
- $\pm\frac{\sqrt{1 – \sin^{2} (-0.84)}}{\sin (-0.84)}$
- $\pm\frac{\cos (-0.84)}{\sqrt{1 – \cos^{2} (-0.84)}}$
- $\pm \sqrt{\csc^{2} (-0.84) – 1}$
- $\pm\frac{1}{\sqrt{\csc^2 (-0.84) – 1}}$
- $\frac{1}{tg\hspace{3px}(-0.84)}$
As the tangent function is the reciprocal of the cotangent function, 1 / tg -0.84 = ctg-0.84.
In the next part of this article we discuss the trigonometric significance of ctg minus 0.84, and there you can also learn what the search calculations form in the sidebar is used for.
What is ctg -0.84?
In a circle with the radius r, the horizontal axis x, and the vertical axis y, -0.84 is the angle formed by the two sides x and r; r moving counterclockwise is the positive angle.
Applying the unit-circle definition found on our homepage, assumed r = 1, in the intersection of the point (x,y) and the circle, y = sin -0.84, x = cos -0.84 and ctg -0.84 = cos -0.84/sin -0.84.
Note that you can locate many terms including the cotangent-0.84 value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of ctg-0.84.
Along the same lines, using the aforementioned form, can you look up terms such as ctg -0.84 value, ctg -0.84, ctg-0.84 value and what is the ctg of -0.84 radians, just to name a few.
Given the periodicity of cotangent of -0.84, to determine the cotangent of an angle < -π, e.g. -7.12318530717959, calculate ctg -7.12318530717959 as ctg (-7.12318530717959 mod π) = cotangent of -0.84, or use our form.
