Where is tan 0

But I always had trouble keeping straight anything much past sine and cosine, so I used the reasoning demonstrated above to figure out the tangent and the other trig graphs.

As long as you know your sines and cosines very well, you'll be able to figure out everything else. Stapel, Elizabeth. Accessed [Date] [Month] Linking to this site School licensing.

The "Homework Guidelines". In the first quadrant, the values for sin, cos and tan are positive. In the second quadrant, the values for sin are positive only. In the third quadrant, the values for tan are positive only.

In the fourth quadrant, the values for cos are positive only. In the fourth quadrant, C os is positive, in the first, A ll are positive, in the second, S in is positive and in the third quadrant, T an is positive. This is easy to remember, since it spells "cast". It is just a very basic concept of trigonometry to find the tangent of the angle using the sine and cosine of the angle.

It is known that the ratio of sine and cosine of the same angle gives the tangent of the same angle. Tan 0 degree in fraction can be expressed as,. It implies that Tan 0 is equal to 0. Before getting stuck into the functions, it helps to give a name to each side of a right triangle:.

Sine , Cosine and Tangent often shortened to sin , cos and tan are each a ratio of sides of a right angled triangle:.

Divide the length of one side by another side. Good calculators have sin, cos and tan on them, to make it easy for you.
