Tangent difference formula
WebRemember: When we use the words 'opposite' and 'adjacent,' we always have to have a specific angle in mind. Range of Values of Sine. 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. WebThe measure of an angle formed by a secant and a tangent drawn from a point outside the circle is 1 2 the difference of the intercepted arcs . Remember that this theorem only used …
