`(sin^(2) 30^(@) + sin^(2) 45^(@) - 4 cot^(2) 60^(@))/(2 sin 30^(@) cos30^(@) + (1)/(2) tan60^(@))` का मान ज्ञात कीजिए |

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^(@))

sin^(2) 60^(@) + 2 tan 45^(@) - cos^(2) 30^(@)

(5sin^(2)30^(@)+cos^(2)45^(@)-4tan^(2)30^(@))/(2sin30^(@).cos30^(@)+tan45^(@))=?

2tan ^ (2) 45 ^ (@) + cos ^ (2) 30 ^ (@) - sin ^ (2) 60 ^ (@)

2tan ^ (2) 45 ^ (@) - + cos ^ (2) 30 ^ (@) - sin ^ (2) 60 ^ (@) is

Prove that: sin^(2)30^(@)cos^(2)45^(@)+4tan^(2)30^(@)+(1)/(2)sin^(2)90^(@)+(1)/(8)cot^(2)60^(@)=2

(sin ^ (2) 30 ^ (@) cos ^ (2) 45 ^ (@) + 4tan ^ (2) 30 ^ (@) + (1) / (2) sin ^ (2) 90 ^ (@) + (1) / (8) cot ^ (2) 60 ^ (@)) =?

(7sin ^ (2) 30 ^ (@) + 3cos ec ^ (2) 60 ^ (@) - cot ^ (2) 45 ^ (@)) / (sin ^ (2) 70 ^ (@) + sin ^ (2) 20 ^ (@)) + 2sin ^ (2) 30 ^ (@) - 2cos ^ (2) 30 ^ (@) 20
