Evaluate : cosec10^@-sqrt3sec10^@

Calculate the following without using trigonometric tables (i) tan 9^(@) - tan 27^(@) - tan 63^(@) + tan 81^(@) (ii) cosec 10^(@) -sqrt(3) sec 10^(@) (iii) 2sqrt(2) sin 10^(@) [(sec 5^(@))/(2) + (cos 40^(@))/(sin 5^(@))-2 sin 35^(@)] (iv) cot 70^(@)+4 cos 70^(@)

Find the value of cosec 10^(@) - sqrt(3) sec 10^(@) .

Find the value of cos ec10^(@)-sqrt(3)sec10^(@)(i)4(ii)2(ii)0(iv)-1

cos ec10 ^ (@) - sqrt (3) sec10 ^ (@) =

The value of cosec 430 ^(@) + sqrt3 sec 470^(@) is :

The value of sqrt3"cosec"20^@ - sec 20^@ is equal to

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