Equations (3) are called half-angle formulas. The sign before the root symbol is selected according to the value of ɸ/2. The sums or differences of trigonometric functions of different arguments can be converted into products according to the following formulas: Here, in the first formula an...
Tangent Formula The tangent formula is: tan(α) =opposite/adjacent=a/b Thus, the tangent of angle α in a righttriangleis equal to the opposite side’s length divided by the adjacent side’s length. To find the ratio of tangent, simply enter the length of the opposite and adjacent and...

The tangent of the angle of inclination of a line, or the slope of the tangent line for a curve or surface. Tangent A tangent line curve, or surface; specifically, that portion of the straight line tangent to a curve that is between the point of tangency and a given line, the given ...
The value of the tangent (ratio) depends only on the size of the angle, not on the particular right triangle used to compute it. The trigonometric law of tangentsis a relationship between two sides of a plane triangleand the tangents of the sum and difference of the angles opposite those...
Identify the part of the triangle in reference to the given angle. Use the appropriate formula derived from the SOHCAHTOA. Solve for the unknown angle by using a scientific calculator. Do not forget to round off to two decimal places. ...
