\left( \frac { \sin 27 ^ { 0 } } { \cos 63 ^ { \circ } } \right) ^ { 2 } + \left( \frac { \cos 63 ^ { 0 } } { \sin 27 ^ { \circ } } \right) ^ { 2 } |

Answer» cos63 = cos(90-27) = cos27 sin27 = sin(90-63) = cos63 (sin27/cos63)*(sin27/cos63) + (cos63/sin27)*(cos63/sin27) = (sin27/sin27)*(sin27/sin27) + (cos63/coa63)*(cos63/coa63) = 1+1 = 2 |
