The other four trigonometric functions (tan, cot, sec, csc) can be defined as quotients and reciprocals of sin and cos, except where zero occurs in the denominator. It can be proved, for real arguments, that these definitions coincide with elementary geometric definitions if the argument is regarded as an angle … 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 convenient. One common unit is degrees, in which a right angle is 90° and a complete turn is 360° (particularly in 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) $${\displaystyle \sin {\frac {\pi }{6}}=\sin 30^{\circ }={\frac {\sqrt {1}}{2}}={\frac {1}{2}}}$$ See more Conventionally, an abbreviation of each trigonometric function's name is used as its symbol in formulas. Today, the most common versions … 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 … See more The six trigonometric functions can be defined as coordinate values of points on the Euclidean plane that are related to the unit circle, which is the circle of radius one centered at the … See more The modern trend in mathematics is to build geometry from calculus rather than the converse. Therefore, except at a very elementary level, trigonometric functions are defined using the methods of calculus. Trigonometric functions are differentiable and See more WebProperties of Trigonometric Functions. The properties of the 6 trigonometric functions: sin (x), cos (x), tan (x), cot (x), sec (x) and csc (x) are discussed. These include the graph, domain, range, asymptotes …
WebCalculus questions and answers. 5. ( 6 pts.) Given x=6csc (θ), find expressions for cos (θ) and sin (θ), with θ in quadrant II. Your answers will be algebraic expressions in terms of x. Show your work. WebNotice also that sin θ = cos (π 2 − θ), sin θ = cos (π 2 − θ), which is opposite over hypotenuse. Thus, when two angles are complementary, we can say that the sine of θ θ equals the cofunction of the complement of θ. θ. Similarly, tangent and cotangent are cofunctions, and secant and cosecant are cofunctions.
