The three basic functions are sine, cosine, and tangent. Here they are:.
sin(A)= opp./hyp.
cos(A)= adj./hyp.
tan(A)= opp./adj.
OR.
sin(A)= opp ÷ hyp
cos(A)= adj ÷ hyp
tan(A)= opp ÷...
Trigonometry is the study of the relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships.
The trigonometric functions give ratios defined by an angle. Whenever you have an angle and a side in right triangle, you can find all the other angles and sides using the six trigonometric functions...
right angled triangle have only three angles and three sides therefore we have three formulae for finding the ratio of three sides but when we have to find the inverse of all we Get three more...
