1. Consider the graph of y = tan x.
\n" ); document.write( "(a) How does it show that the tangent of 90 degrees is undefined?
\n" ); document.write( "It has a vertical asymptote at x=90 degrees
\n" ); document.write( "--------
\n" ); document.write( "(b) What are other undefined x values?
\n" ); document.write( "90 degrees + and 180n degrees - 180n degrees where n=1,2,3,....
\n" ); document.write( "---------------------
\n" ); document.write( "(c) What is the value of the tangent of angles that are close to 90 degrees
\n" ); document.write( "(say 89.9 degrees and 90.01 degrees)?
\n" ); document.write( "They approach infinity from below 90 and approach -infinity as they approach
\n" ); document.write( "90 degrees from above.
\n" ); document.write( "--------------------
\n" ); document.write( "(d) How does the graph show this?
\n" ); document.write( "Asymptotes
