Short Answer

Expert verified

Two negative angles arecost=-22,tant=-1and positive angles aresint=22,csct=22

Step by step solution

01

Step 1. Given information .

Consider the given points-22,22.

02

Step 2. Finding negative and positive angles.

We follow the definition of six trigonometric function using P=-22,22=x,ywhere x=-22,y=22

sint=y=22,cost=x=-22,tant=yx=-1csct=22,sect=-22
