Question 1018897
{{{((1/cos(x))/sin(x))-(cos(x)/sin(x))=(1/sin(x))(1/cos(x)-cos(x))}}}
{{{((1/cos(x))/sin(x))-(cos(x)/sin(x))=(1/sin(x))(1/cos(x)-cos^2(x)/cos(x))}}}
{{{((1/cos(x))/sin(x))-(cos(x)/sin(x))=(1/sin(x))((1-cos^2(x))/cos(x))}}}
{{{((1/cos(x))/sin(x))-(cos(x)/sin(x))=(1/sin(x))((sin^2(x))/cos(x))}}}
{{{((1/cos(x))/sin(x))-(cos(x)/sin(x))=sin(x)/cos(x)}}}
{{{((1/cos(x))/sin(x))-(cos(x)/sin(x))=tan(x)}}}
