2e tan A5^(@)cot60^(@)=sin30^(@)cosec60^(@)

Evaluate the following : (sin30^(@)+tan45^(@)-cosec60^(@))/(sec30^(@)+cos60^(@)+cot45^(@))

Evaluate (sin30^(@)+tan45^(@)-cosec60^(@))/(sec30^(@)+cos60^(@)+cot45^(@))

Find the value of following expressions : (i) sec^(2)60^(@)cos^(2)45^(@)-cosec^(2)30^(@) (ii) (tan45^(@)cot^(2)60^(@)+tan^(2)30^(@)cot45^(@))/(sin30^(@)+cos60^(@))

Find the value of (sin30^(@)+tan45^(@)-csc60^(@))/(sec30^(@)+cos60^(@)+cot45^(@))

Evaulate : 4-(sin30^(@)+tan45^(@)-"cosec"60^(@))/(sec30^(@)+cos60^(@)+cot45^(@))

Calculate : sec^(2)60^(@)-cot^(2)30^(@)-(2tan30^(@)"cosec"60^(@))/(1+tan^(2)30^(@)) .

Evaluate : (sin^(2)30^(@)+sin^(2)45^(@)-4cot^(2)60^(@))/(2sin30^(@)cos30^(@)+(1)/(2)tan60^(@))

Evaluate : (sin^(2)30^(@)+sin^(2)45^(@)-4cot^(2)60^(@))/(2sin30^(@)cos30^(@)+(1)/(2)tan60^(@))

Calculate : (tan60^(@)-tan30^(@))/(1+tan60^(@) tan30^(@))+cos60^(@) cos30^(@)+sin60^(@) sin 30^(@) .
