Here ∠CAB is an acute angle. Observe the position of the sides with respect to angle A.
- BC is the opposite side of Angle A.
- AB is the adjacent side with respect to angle A.
- AC is the hypotenuse of the right angled triangle ABC.
The trigonometric ratios of the angle A in the right angled triangle ABC can be defined as follows.
sinA=HypotenuseSideoppositetoangleA=ACBC
cosA=HypotenuseSideadjacenttoangleA=ACAB
tanA=SideadjacenttoangleASideoppositetoangleA=ABBC
cscA=SideoppositetoangleAHypotenuse=BCAC
secA=SideadjacenttoangleAHypotenuse=ABAC
cotA=Sideoppositet
