The identities of tangent -0.99 are as follows:
= ctg (π/2 + 0.99) = ctg 2.5607963267949
-tg-0.99
= tg (0.99) = -tg -0.99
= ctg (π/2 – 0.99) = ctg 0.580796326794897
= tg (π + 0.99) = tg 4.13159265358979
There are more formulas for the double angle (2 × -0.99), half angle ((-0.99/2)) as well as the sum, difference and products of two angles such as -0.99 and β.

In terms of the other five trigonometric functions, tg of -0.99 =
- $\pm\frac{\sin (-0.99)}{\sqrt{1 – \sin^{2} (-0.99)}}$
- $\pm\frac{\sqrt{1 – \cos^{2} (-0.99)}}{\cos (-0.99)}$
- $\pm \sqrt{\sec^{2} (-0.99) – 1}$
- $\pm\frac{1}{\sqrt{\csc^2 (-0.99) – 1}}$
- $\frac{1}{ctg\hspace{3px}(-0.99)}$
As the cotangent function is the reciprocal of the tangent function, 1 / ctg -0.99 = tg-0.99.
In the next part of this article we discuss the trigonometric significance of tg minus 0.99, and there you can also learn what the search calculations form in the sidebar is used for.
What is tg -0.99?
In a circle with the radius r, the horizontal axis x, and the vertical axis y, -0.99 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 -0.99, x = cos -0.99 and tg -0.99 = sin -0.99/cos -0.99.
Note that you can locate many terms including the tangent-0.99 value using the search form. On mobile devices you can find it by scrolling down. Enter, for instance, value of tg-0.99.
Along the same lines, using the aforementioned form, can you look up terms such as tg -0.99 value, tg -0.99, tg-0.99 value and what is the tg of -0.99 radians, just to name a few.
Given the periodicity of tangent of -0.99, to determine the tangent of an angle < -π, e.g. -7.27318530717959, calculate tg -7.27318530717959 as tg (-7.27318530717959 mod π) = tangent of -0.99, or look it up with our form.
