WebThe sine of an angle has a range of values from -1 to 1 inclusive. Below is a table of values illustrating some key sine values that span the entire range of values. The Cosine Ratio The cosine of an angle is always the ratio of the (adjacent side/ hypotenuse). c o s i n e ( a n g l e) = adjacent side hypotenuse Example 1 WebTrigonometry - Sin, Cos, Tan, Cot A circle centered at the origin of the coordinate system and with a radius of 1 is known as a unit circle . If P is a point from the circle and A is the angle between PO and x axis then: The x -coordinate of P is called the cosine of A and is denoted by cos A ;

While right-angled triangle definitions allow for the definition of the trigonometric … See more In mathematics, the trigonometric functions (also called circular functions, angle functions or goniometric functions ) are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely … See more In geometric applications, the argument of a trigonometric function is generally the measure of an angle. For this purpose, any angular unit is … See more The algebraic expressions for the most important angles are as follows: $${\displaystyle \sin 0=\sin 0^{\circ }\quad ={\frac {\sqrt {0}}{2}}=0}$$ (zero angle) Writing the … See more Many identities interrelate the trigonometric functions. This section contains the most basic ones; for more identities, see List of trigonometric identities. These identities may be proved … See more Conventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. Today, the most common versions of these abbreviations are "sin" for sine, … See more If the acute angle θ is given, then any right triangles that have an angle of θ are similar to each other. This means that the ratio of any two side lengths depends only on θ. Thus these six ratios define six functions of θ, which are the trigonometric functions. In the following … See more The modern trend in mathematics is to build geometry from calculus rather than the converse.
