Express \(Sine(sin)\), \(Cosine(cos)\) and \(tangent(tan)\) in terms of sides of triangle
Question : Express \(Sine(sin)\), \(Cosine(cos)\) and \(tangent(tan)\) in terms of sides of triangle Answer : For a right angle triangle we can find sine or sin, cosine or cos, tangent or tan in terms of their side. To know more accurately about sin, cos and tan we must have to know about (1)base, (2)height (perpendicular) and (3)hypotenuse. Figure-1 (right angle triangle) In general we use base, hypotenuse and height(perpendicular) as shown in figure. But this method is not always right. Let's know what is right (1) Definition of hypotenuse: The side opposite to the right angle or \(90^{o}\) is called hypotenuse, it is the largest side of right angle triangle. (2) Definition of perpendicular: It depends on the angle which we are going to consider. If we consider angle C the perpendicular is AB. If we consider angle A then perpendicular is BC. (See be...
