point P is on the terminal side of angle theta. Evaulate the six trigonometric functions for theta. P(-4,-6)
\n" ); document.write( "-------------------------------
\n" ); document.write( "x,y, and r determine the trig ratios.
\n" ); document.write( "You are given x and y; so you can find r = sqrt(x^2+y^2) = sqrt(16 + 36)
\n" ); document.write( "= sqrt(52) = 2sqrt(13)
\n" ); document.write( "x = -4,
\n" ); document.write( "y = -6
\n" ); document.write( "=========================
\n" ); document.write( "sin = y/r = -6/2sqrt(13)
\n" ); document.write( "cos = x/r = -4/2sqrt(13)
\n" ); document.write( "tan = y/x = -6/-4
\n" ); document.write( "-------------------------
\n" ); document.write( "Each of these fractions may be reduced.
\n" ); document.write( "Then csc, sec, and ctn are the inverse of sin, cos, and tan.
