Find the number of values of x belonging to( -2pie to 2pie ) satisfying tan x + cot x = 2cosec x \n" ); document.write( "------------- \n" ); document.write( "tan x + cot x = 2cosec x \n" ); document.write( "sin/cos + cos/sin = 2/sin \n" ); document.write( "sin^2/cos + cos = 2 \n" ); document.write( "sin^2 + cos^2 = 2cos \n" ); document.write( "2cos = 1 \n" ); document.write( "cos = 1/2 \n" ); document.write( "x = -5pi/3, -pi/3, pi/3, 5pi/3 \n" ); document.write( "=============== \n" ); document.write( "PS It's the Greek letter pi, not the dessert, pie. \n" ); document.write( " \n" ); document.write( " |
