Examples: Find the values of sin(θ),cos(θ),tan(θ),csc(θ),sec(θ),cot(θ).

sin(θ)=5/13                            csc(θ)=13/5

cos(θ)=12/13                         sec(θ)=13/12          

tan(θ)=5/12                            cot(θ)=12/5

Example: Find the hypotenuse of the triangle given a side and an angle.
