Question 1203873
{{{ tan (theta) cot (theta) = 1 }}}

Use trigonometric identities: {{{ tan (theta)= sin (theta)/cos(theta) }}} and {{{ cot (theta) =cos(theta)/sin (theta) }}}


{{{ tan (theta) cot (theta)  }}}


={{{ (sin (theta)/cos(theta))*(cos(theta)/sin (theta)) }}}


={{{ (cross(green(sin (theta)))1)/(cross(cos(theta))1)*(cross(cos(theta))1)/(cross(green(sin (theta)))1) }}}


= {{{ 1 }}}
