For any triangles with vertex angles and corresponding opposite sides are A, B, C and a, b, c, respectively, the sine law is given by the formula $\dfrac{a}{\sin 


This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides many practice problems on identifying the sides that are opposite and adjacent to a given angle.

The graph of the function y = A sin Bx has an amplitude of A and a period of Sine waves traveling in two directions in space can be represented as u ( t , x ) = A sin ⁡ ( k x − ω t + φ ) {\displaystyle u(t,x)=A\sin(kx-\omega t+\varphi )} When two waves having the same amplitude and frequency , and traveling in opposite directions, superpose each other, then a standing wave pattern is created. Sine of the Angle: 270° sin (270°) = -1 (smallest value that sine can have) 330° sin (330°) = -½: 0° sin(0°) = 0: 30° sin(30°) = ½: 90° sin(90°) = 1 (greatest value that sine can have) Pi is a concept that just happens to show up in circles: Sine is a gentle back and forth rocking Pi is the time from neutral to max and back to neutral n * Pi (0 * Pi, 1 * pi, 2 * pi, and so on) are the times you are at neutral To find the sine of a particular number, we have to first write =SIN () in a particular cell. As you can see from the above screenshot, the SIN function in Excel expects a number as an input. This number usually represents a value in radians. So in this case, we will write “=SIN (1.0472)”, where 1.0472 is the radians equivalent of 60 degrees. If θ is one of the acute angles in a triangle, then the sine of theta is the ratio of the opposite side to the hypotenuse, the cosine is the ratio of the adjacent side to the hypotenuse, and the tangent is the ratio of the opposite side to the adjacent side.

Sin Cos formulas are based on sides of the right-angled triangle. Sin and Cos are basic trigonometric functions along with tan function, in trigonometry. Sine of angle is equal to the ratio of opposite side and hypotenuse whereas cosine of an angle is equal to ratio of adjacent side and hypotenuse. Sin θ =. Cos θ =.

The Extended Law of Sines is used to relate the radius of the circumcircle of a triangle   Since the equation is true for any angle, it is an identity. We can use this identity to continue the graph of the sine function in either direction.

Notice that an angle and its opposite side are the same letter. Test items assessed participants' ability to identify graphed reflections and vertical and horizontal shifts for cubic, square, logarithmic, exponential, and sine formulas.
