There aren't. There are three: Sine, Cosine and Tangent, for any given right-angled triangle.
They are related of course: for any given angle A, sinA/cosA = tanA; sinA + cosA =1.
As you can prove for yourself, the first by a little algebraic manipulation of the basic ratios for a right-angled triangle, the second by looking up the values for any value such that 0 < A < 90.
And those three little division sums are the basis for a huge field of mathematics extending far beyond simple triangles into such fields as harmonic analysis, vectors, electricity & electronics, etc.

What is the difference between negative sine and cosine graphs and positive sine and cosine graphs?
The negative sine graph and the positive sine graph have opposite signs: when one is negative, the other is positive - by exactly the same amount. The sine function is said to be an odd function. The two graphs for cosine are the same. The cosine function is said to be even.
What is cosine 0?
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
Can trigonometric functions sine cosine and tangent be used in triangles other than right triangles?
Yes, trigonometric functions such as sine, cosine, and tangent can be applied to triangles other than right triangles through the use of the Law of Sines and the Law of Cosines. These laws relate the ratios of the sides of any triangle to the sines and cosines of their angles, allowing for the calculation of unknown sides and angles in non-right triangles. Thus, trigonometric functions are versatile tools applicable to various types of triangles.
What is a sine ratio?
The Sine ratio is Sine(angle) = opposite side / hypotenuse side. This is written in 'short-hand' as Sin(angle) = o / h Similarly the cosine ratio is Cosine(angle) = adjacent side / hypotenuse side. Cos(angle) = a/h Similarly the tangent ratio is Tangent(angle) = opposite side /adjacent side. Tan(angle) = o/a NB THe sides refer to the sides of a right-angled triangle. NNB The angle referred to is NOT the right angle, but a selected angle from the other two angles.
What is the difference between a sine graph and a cosine graph?
Oh, dude, it's like asking the difference between a hot dog and a hamburger. So, like, the main difference is just a phase shift of 90 degrees. Sine starts at zero, cos starts at one, but they're basically like two sides of the same math coin.
What are trigometric ratios?
Trigonometric ratios are ratios of the sides of a right triangle, involving the lengths of the sides and the angles of the triangle. The main trigonometric ratios are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan respectively. These ratios are used in trigonometry to relate the angle of a right triangle to its side lengths.
How do you solve for a triangle with two angles but no lengths?
you can use the sine, cosine, tangent formula.
How do you know when to use tangent cosine or sine?
It depends on what information you already have. For example, if you know the length of two sides of a triangle, you can easily find the tangent. Or, if you know the length of two angles and a side, you can find the other sides as well, using the tangent, cosine, and sine as needed.
A ratio of the lengths of two sides of a right triangle?
Sine Cosine Tangent Cotangent Secant Cosecant
If two integers have the same sign what is the sine of their sum?
Sine(A+ B) = Sine(A)*Cosine(B) + Cosine(A)*Sine(B).
How does the unit circle relate to sin cos and tan?
Sine: the y-coordinate. Cosine: the x-coordinate. Tangent: the ratio of the two (y/x).
How do you figure the base of a triangle when you know the dimension of the other two sides?
If it is a right triangle, you can use the Pythagorean Theorem. If you know the angle measures, you can use cosine/sine/tangent.
What is the difference between negative sine and cosine graphs and positive sine and cosine graphs?

What is trigonometric ratio?
It is the relationship between a given angle and two of the sides of a triangle. There are three ratios , viz; Sine(Sin), Cosine(Cos) and Tangent(Tan). Mathemtically written as Sin(angle) = opposite/hypotenuse Cos(angle) = adjacent / hypotenuse Tan(angle) = opposite/ adjacent. NB The angle referred to is NOT the right angle. NNB The word 'Sine' is from Latin, and means curve. If you extend the Sine function beyond 360 degrees, , and plot it on a graph, you find it makes a wave-like curve. Cos mean 'Complementary Sine'. NNNB All refers to an right-angled(90 degree) triangle.
How do you find the width and length of a rectangle knowing ONLY the diagonal and its angle?
By using the trigonometric ratios of Sine and Cosine. The diagonal forms the hypotenuse of a right angled triangle with the length and width of the rectangle forming the other two sides of the triangle - the adjacent and opposite sides to the angle. Then: sine = opposite/hypotenuse → opposite = hypotenuse x sine(angle) cosine = adjacent/hypotenuse → adjacent = hypotenuse x cosine(angle)
What is cosine 0?
Cosine (0) = 1 Sin(0) = 0 The sine and cosine curves are two intertwining curves, that complement each other, hence the words 'Sine (Curve) and Cosine ( COmplementary Curve).
How can you find the angles of a right triangle with sides 20 21 and 29?
Because it's a right angle triangle use any of the trigonometrical ratios to find the two interior acute angles: tangent = opp/adj, sine = opp/hyp and cosine = adj/hyp The angles are to the nearest degree 46 and 44
