`(sqrt3/sin20^@-1/cos20^@)=4`

Prove that, sqrt3/(sin 20^(@))-1/(cos 20^(@))=4

(sqrt3)/(sin(20^@))-1/(cos(20^@))=

sqrt3 cot20^(@)-4cos20^(@)=

sqrt(3)cot20^(@)-4cos20^(@)=

(sqrt(3))/(sin20^(@)) - (1)/(cos20^(@)) =

sqrt3 cosec 20^(@) -sec 20^(@)= (sqrt3)/(sin(20^(@)))-(1)/(cos (20^(@)))=

In the following questions, write 'T' for ture and 'F' for false statements. sin20^@ (3-4cos270^@) = sqrt3/2
