what is the relationship between cotangent theta and cotangent NEGATIVE theta?
\n" ); document.write( "cot(x)=-cot(-x) (this is called an odd function, compared to an even function)
\n" ); document.write( "Examples:
\n" ); document.write( "pick angle of 45º in quadrant I
\n" ); document.write( "this gives you a reference angle of 45º where cot 45º=1
\n" ); document.write( "-45º will also give you a reference angle of 45º but in quadrant IV where cot -45=-1
\n" ); document.write( "..
\n" ); document.write( "pick angle 135º in quadrant II
\n" ); document.write( "this gives you a reference angle of 45º where cot135º=-1
\n" ); document.write( "-135º will also give you a reference angle of 45º but in quadrant III where cot-135º=1
\n" ); document.write( "..
\n" ); document.write( "pick angle 225º in quadrant III
\n" ); document.write( "this gives you a reference angle of 45º where cot225º=1
\n" ); document.write( "-225º will also give you a reference angle of 45º but in quadrant II where cot-225º=-1
\n" ); document.write( "..
\n" ); document.write( "note: I used a reference angle of 45º for the examples but this will hold true for any reference angle.
\n" ); document.write( "This will also hold true for the tan function since cot is the reciprocal of tan.
\n" ); document.write( "A negative angle means rotating in a clockwise direction and a positive angle in a counter-clockwise direction.The value for the trig functions and their reciprocals is computed from the reference angle and the sign depends on which of the 4 quadrants the angle is in. See if you can apply this method to the sin and cos functions.
