Find the value of tan44 ` cot45 ` tan46 ' Find the value of tan44 ` cot45 ` tan46 ' Note: tan44'means tan60 degree, and "'" means "degree". In addition, this is an exercise in the geometry book of grade three Note: tan44 'means tan44 degree, and "'" means "degree". In addition, this is an exercise in the geometry book of grade three (I'm sorry that the above caption is wrong) I don't understand what's written on the first floor

=sin44/cos44*1*sin46/cos46
=cos46/cos44*(cos44/cos46)
=1
