\n" ); document.write( "Find the values of Sin, Tan, Cos, Cot, Sec, and Csc for the argument.\r
\n" ); document.write( "\n" ); document.write( "1. 5pi/4\r
\n" ); document.write( "\n" ); document.write( "2. 2pi/3\r
\n" ); document.write( "\n" ); document.write( "3.5pi/6\r
\n" ); document.write( "\n" ); document.write( "4. -7pi/4
\n" ); document.write( "I didn't know how to do these because they aren't angles. Thanks!
\n" ); document.write( "
\"5pi%2F4\", converted to degrees = \"225\"
\n" ); document.write( "\"sin+%28225%5Eo%29\" has a reference angle of \"45%5Eo\", but is in the 3rd quadrant, where sin is < 0 (negative).
\n" ); document.write( "Therefore, \"sin+%28225+%5Eo%29\" = \"-+sin+%2845%5Eo%29\" = \"highlight_green%28-+sqrt%282%29%2F2%29\". This is the EXACT VALUE of \"sin+%285pi%2F4%29\". Follow this and try to do the rest.\r
\n" ); document.write( "\n" ); document.write( "You can also use the UNIT CIRCLE to determine the EXACT VALUES of all of the above. \n" ); document.write( "
