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!
cosecant In trigonometry, a function of an angle in a right-angled triangle found by dividing the length of the hypotenuse( the longest side ) by the length of the side opposite the angle. Thus the cosecant of an angle A,usually shortened to cosec A , is always greater than(or equal ...
