For those comfortable in "Math Speak", the domain and range of Sine is as follows. Domain of Sine = all real numbers; Range of Sine = {-1 ≤ y ≤ 1} The 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. WebConventionally, it is given by the right-hand rule, where one simply points the forefinger of the right hand in the direction of a and the middle finger in the direction of b. Then, the vector n is coming out of the thumb (see the adjacent picture). Using this rule implies that the cross product is anti-commutative; that is, b × a = −(a × b). broward county conventional loan limit
