Question 1: Give some properties of tangents to a circle. Answer:The properties are as follows: The tangent line never crosses the circle, it just touches the circle. At the point of tangency, it is perpendicular to the radius. A chord and tangent form an angle and this angle is the ...
A circular function coordinate can be found using the formula (r cos(x),r sin(x)). Here r is the radius of the circle and x is the angle.What are Circular Functions? The trigonometric, or trig, functions, such as sine, cosine, and tangent, are also called circular functions. They ...

Since the radius of the circle is unity, the central angle in radian measurement is measured by the same number as the arc. Consequently, cos ɸ and sin ɸ may be considered the cosine and sine of an angle. In general, the argument of a trigonometric function is considered to be a ...

Circle, geometrical curve, one of the conic sections, consisting of the set of all points the same distance (the radius) from a given point (the centre). A line connecting any two points on a circle is called a chord, and a chord passing through the cent
Angle of elevation = 60° Therefore, using the formula of the tangent function, we have tan 60° = 15/x ⇒ √3 = 15/x ⇒ x = 15/√3 = 5√3 ft. Answer:The length of the shadow is 5√3 ft. Tangent Function Questions ...
