These are sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot). Fig 1: Trig Ratios Chart FIg 1 displays a chart that can be used to recall the six basic trigonometric ratios. The values of these six trigonometric ratios remain positive in the...
When most people talk about trigonometric identities, however, they mean one of the following broader categories of identities. Pythagorean Identities –These include $sin^2x+cos^2x=1$ and related identities, such as $sin^2x=1-cos^2x$. Reciprocal Identities –One divided by sine is cosecant ...
We have just learnt the formulae involving the identities, sin ( A + B ), sin ( A – B ) and so on. Now we shall discuss about the identities that help convert the product of two sines or two cosines or one sine and one cosine into the sum or difference of two sines or two c...
The amount of 75 can be found by subtracting 45 from 120, so the difference identities can be used to find the trigonometric values. Sine Step 1: Set up the trigonometric identity sin(120−45)=sin(120)cos(45)−cos(120)sin(45) ...

The results show that although TAG3P did successfully discover all three popular trigonometric identities of the trigonometric function cos(2x), namely, sin(2x+蟺/2), sin(蟺/2-2x) and 1-2sin 2 (x), it had a tendency to converge towards the first two identities....
