Question 1138393

A reference angle is an angle whose measure is between {{{0}}}° and{{{ 90}}}° (not including {{{0}}}° or {{{90}}}°)

If {{{theta}}} is your angle, here’s how to find its reference angle.

Quadrant |Reference Angle
 II............ |< {{{180}}}° - {{{theta}}}
 III ...........|< {{{theta}}} - {{{180}}}°
 IV............| < {{{360}}}° - {{{theta}}}


=> {{{sin (236 )}}} ° 

= > {{{ 236 }}} ° is in Q II where sin is negative, so reference angle is: {{{236-180=56 }}}

=>{{{sin (236 ) = -sin (56)}}}
