But we can in fact find the tangent of any angle, no matter how large, and also the tangent of negative angles.
If you’re stuck on how to solve a problem, try defining it and breaking it into smaller pieces.
Choose whether to approach the problem logically or whether you should think about how the outcome might make you feel.
This formula which connects these three is: cos(angle) = adjacent / hypotenuse therefore, cos60 = x / 13 therefore, x = 13 × cos60 = 6.5 therefore the length of side x is 6.5cm. The following graphs show the value of sinø, cosø and tanø against ø (ø represents an angle).
From the sin graph we can see that sinø = 0 when ø = 0 degrees, 180 degrees and 360 degrees.
So if we have any two of them, we can find the third. From our calculator we find that tan 60° is 1.733, so we can write Transposing: which comes out to 26, which matches the figure above.
For every trigonometry function such as tan, there is an inverse function that works in reverse.The Law of Tangents is a rather obscure trigonometric identity that is sometimes used in place of its better-known counterparts, the law of sines and law of cosines, to calculate angles or sides in a triangle.If and are angles in a triangle opposite sides and respectively, then Let and denote , , respectively.In any right triangle, the tangent of an angle is the length of the opposite side (O) divided by the length of the adjacent side (A). As an example, let's say we want to find the tangent of angle C in the figure above (click 'reset' first). So we can write This division on the calculator comes out to 0.577.From the formula above we know that the tangent of an angle is the opposite side divided by the adjacent side. So we can say "The tangent of C is 0.5776 " or If we look at the general definition - we see that there are three variables: the measure of the angle x, and the lengths of the two sides (Opposite and Adjacent). We know that the tangent of A (60°) is the opposite side (26) divided by the adjacent side AB - the one we are trying to find.
