Sin and Cos are basic trigonometric functions along with tan functions, in Trigonometry which is a part of Mathematics. Sin Cos formulas are always based on the sides of the given right-angled triangle. Other operations involving trigonometric functions. Sine/Cos/Tan SOHCAHTOA Sine, Cosine and Tangent Opposite & adjacent sides and SOHCAHTOA of angles This page explains the sine, cosine, tangent ratio, gives on an overview of their range of values and provides practice problems on identifying the sides that are opposite and adjacent to a given angle. And tan is opposite over adjacent, which means tan is sin/cos. R ≔ 3 8 + 1 8 5 − 5 − 2 5 + 1 3 16 + 2 5 + 1 16Įxpanding and simplifying trigonometric functions. įor information about expanding and simplifying trigonometric expressions, see expand, factor, combine/trig, and simplify/trig. The area of the sector is half the square of the radius times the angle, where, again, the angle is measured in radians.
To convert from degrees to radians, multiply the number of degrees by /180. Three examples are that (1) any trigonometric expression can be converted to an expression in terms of only sin and cos, (2) expressions involving exp(x) can be converted to their hyperbolic forms, and (3) a trigonometric function with an argument of the form q π, where q is a rational, can in some cases be converted to radical form. The length of the arc is just the radius r times the angle where the angle is measured in radians. Also available are conversion routines that will convert trigonometric expressions to other forms. Their reciprocals are respectively the cosecant.
Maple also provides simplification and expansion procedures that apply most of the common trigonometric and hyperbolic identities. The trigonometric functions most widely used in modern mathematics are the sine, the cosine, and the tangent. (1 radian = 180/Pi degrees).įor trigonometric functions that accept arguments in degrees, see trigd. Arguments for all trigonometric functions
