`(1/3cos30)/(1/2sin45)+tan60/cos30`

The value of ((1)/(3)cos30^(@))/((1)/(2)sin45^(@))+(tan60^(@))/(cos30^(@))=

(tan60^@)/(sin60^@+cos30^@)

sqrt((1+cos30)/(1-cos30))=sec60+tan60

Evaluate: ((sin 30)^2+(cos 45)^2-4(sin 30)^2)/(2sin 30 cos 30+tan 45)

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^(@))

The value of (4 tan^2 30+1/4 sin^2 90+ 1/8 cot^2 60+ sin^2 30. cos^2 45)/ (sin60.cos30-cos60.sin30) is/ (4 tan^2 30+1/4 sin^2 90+ 1/8 cot^2 60+ sin^2 30. cos^2 45)/ (sin60.cos30-cos60.sin30) का मान है
