The value of tan 180 degrees is equal to 0. Learn how to find the value of tan 180 degrees and how to derive the formula for tan 180 minus theta, here at BYJU’S today!
Therefore, tan formulas are $\tan \theta = \dfrac{{\sin \theta }}{{\cos \theta }}$ and $\tan \theta = \dfrac{{BC}}{{AB}}$ . 90-Degrees Angle An angle of $90$ degrees is created when two straight lines cross perpendicularly. In other words, the angle between two radii of ...

Prove thattan(70)−tan(50)+tan(10)=3. Tangent Function: In trigonometry, the tangent of an angle refers to the ratio of the opposite side and the adjacent side of a right triangle. Tangent function is an odd function and is unbounded. Its value is positive in the first ...
To convert an inverse tangent (tan-1) to an inverse sine (sin-1), use the identity tan-1(x) = sin-1(x/√(1+x2)). We can understand this formula by looking at a righttrianglewith an angle theta and the opposite sidexand adjacent side 1. ...
