`4cos36^@+co t 7 1 /2^@=`

Prove that 4 cos 36^@ +cot 7 1^@/2 = sqrt1+sqrt2 +sqrt3+ sqrt4+ sqrt5+ sqrt6 .

4 cos 36^(@) + cot 7 (1^(@))/(2)=

4cos36 ^ (@) + cos (7 (1) / (2)) ^ (0) =

4cos36^(@)+cot(7(1)/(2))^(@)=

4 cos 36^(circ)+cot (7 (1)/(2))^(circ)=

4 cos 12 ^(@) cos 48^(@) cos 72^(@) = cos 36 ^(@)

In the following questions, write 'T' for ture and 'F' for false statements. cos15^@ cos7(1)/2^@ sin7(1)/2^@ = 1

Statement-1: (cos36^(@)-cos72^(@))/(cos36^(@)cos72^(@))=2 Statement-2: sin15^(@)=(sqrt6-sqrt7)/(4)

Statement-1: (cos36^(@)-cos752^(@))/(cos36^(@)cos72^(@))=2 Statement-2: sin15^(@)=(sqrt6-sqrt7)/(4)
