Find the exact values of the six trigonometric function of θ if the terminal side of θ in standard position contains the point (-5,-4).
\n" ); document.write( "--------------
\n" ); document.write( "All of the trig functions depend on x,y and r.
\n" ); document.write( "------------------------------
\n" ); document.write( "Since your angle passes thru (-5,-4) you know x=-5 and y=-4.
\n" ); document.write( "So, r = sqrt(25+16) = sqrt(41)
\n" ); document.write( "-----------
\n" ); document.write( "Note: also your point is in the 3rd quadrant
\n" ); document.write( "----------
\n" ); document.write( "So,
\n" ); document.write( "sin = y/r = -4/sqrt(41)
\n" ); document.write( "cos = x/5 = -5/sqrt(41)
\n" ); document.write( "tan = y/x = 4/5
\n" ); document.write( "---------------
\n" ); document.write( "The csc, sec, and cot are the inverse of sin, cos, and tan.
