(a) The point  is  \"\" \"\"

\

Step 1:

\

The above coordinate pair in first quadrant.

\

Angle \"\" is in first quadrant.

\

Graph:

\

\"\".

\

From Pythagorean theorem,

\

\"\"

\

\"\"

\

\"\"

\

\"\".

\

Step 2:

\

Six trigonometric functions are

\

\"\", \"\", \"\",

\

\"\", \"image\", \"\".

\

Substitute the values of  \"\" in above ratios

\

\"\", \"\", \"\",
