Question

a) Evaluate: cos37.cosec53 tan5 .tan25 .tan45 .tan65 .tan85 urgent

Answer 1

Answer:

Ans: 1

Step-by-step explanation:

cos37.cosec53 tan5 .tan25 .tan45 .tan65 .tan85

sin(90-37)*cosec53 *tan5*tan25*1*tan(90-65)*tan(90-5)

=sin53*1/sin53 * tan5*tan(90-5)*tan(25)*tan(90-65)*1

=1*tan5*cot5 *tan25*co25

=1*tan5*1/tan5*tan25*1/tan25

=1*1*1=1
