Home ›Calculators›Math Calculators› Tangent calculator Tangent Calculator. Determine what quadrant the terminal side of the angle lies in (the initial side of the angle is along the positive x-axis). Method 1: Decimal. To calculate the angle of a right triangle, sine cosine tangent formula is used. A—the amplitude of the function; typically, this is measured as the height from the center of the graph to a maximum or minimum, as in sin⁡(x) or cos⁡(x). First, measure the angle. If we look at the general definition - tan x=OAwe see that there are three variables: the measure of the angle x, and the lengths of the two sides (Opposite and Adjacent).So if we have any two of them, we can find the third.In the figure above, click 'reset'. Circle Tangent Arrow - Calculator. A right angle looks like this: It can handle horizontal and vertical tangent lines as well. Refer to the figure below. In this graph, we can see that y=tan⁡(x) exhibits symmetry about the origin. The figure below shows y=tan⁡(x) (purple) and (red). Depending what quadrant the terminal side of the angle lies in, use the equations in the table below to find the reference angle. Tangent Tables Chart of the angle 0° to 90° for students. tangent (0°) = 0. tangent (16°) = 0.28675. tangent (32°) = 0.62487. tangent (1°) = 0.01746. tan ( α + β) = (tan α + tan β) / (1 - tan α tan β) Angles difference. The other commonly used angles are 30° (), 45° (), 60° () and their respective multiples. Tangent also known as tan relates the angles and sides of a triangle. Once we determine the reference angle, we can determine the value of the trigonometric functions in any of the other quadrants by applying the appropriate sign to their value for the reference angle. Sum of Tangent Angles. Referencing the figure above, we can see that each period of tangent is bounded by vertical asymptotes, and each vertical asymptote is separated by an interval of π, so the period of the tangent function is π. To calculate angles in a polygon, first learn what your angles add up to when summed, like 180 degrees in a triangle or 360 degrees in a quadrilateral. Below is a table of tangent values for commonly used angles in both radians and degrees. An inverse tan, also known as tangent, is the inverse of the tangent function or opposite. Formulas.
