1 thought on “how can u say that the trigonometric ratios are related to a circle”
Answer:
tan means Tangent what does the ratio of Opposite side to Adjacent side have to do with the tangent of a circle? Similarly, sec means Secant; How does ratio of hypotenuse to Adjacent side have to do with the secant of a circle?
Trigonometric ratios all apply only to a right angled triangle but still the names of the ratios suggest relations to entities related to circles.
