The cosine is a trigonometric function that relates to an angle θ in a right triangle to the ratio of the length of the side adjacent the angle and the length of the longest side (hypotenuse) of the triangle. A right triangle has one angle that measures 90° or π/2 radians which is...
We can find anunknown anglein aright-angled triangle, as long as we know the lengths oftwo of its sides. Example The ladder leans against a wall as shown. What is theanglebetween the ladder and the wall? The answer is to useSine, Cosine or Tangent!
Note that the tangent of a circle is perpendicular to the radius, i.e., the lines joining the points O, A, and T forms a right-angled triangle. The equation of tangent of a circle is also based on Pythagoras's theorem. The length of the lines OA, AT, and OT can be given by th...
