WebWhen dealing with right triangles (triangles that have one 90 degree angle) in trigonometry, the biggest things to realize is that no matter what size the triangle is, the ratios of the lengths of the sides stay the same. So, it is very natural to give these ratios names – and that’s where the right triangle definitions of the trig functions comes from! WebWe use it when we know what the tangent of an angle is, and want to know the actual angle. See also arctangent definition and Inverse functions - trigonometry Large and negative angles. In a right triangle, the two variable angles are always less than 90° (See Interior angles of a triangle).But we can in fact find the tangent of any angle, no matter how large, …
