Which of these functions has period 7?
\n" ); document.write( "A. y= sin(7/pi)x
\n" ); document.write( "B. y= cot(7/pi)x
\n" ); document.write( "C. y= cos(pi/7)x
\n" ); document.write( "D. y= tan(pi/7)x
\n" ); document.write( "--------------------
\n" ); document.write( "sine & cosine of x --> period of 2pi
\n" ); document.write( "tan and cot of x --> period of pi
\n" ); document.write( "---
\n" ); document.write( "tan(pi*x) --> period of 1
\n" ); document.write( "tan (pi*x/7) --> period of 7
\n" ); document.write( "
\n" );
