निम्नलिखित के सांख्यिक मान परिकलित करें:
`sin^(2) 60^(@) - cos^(2) 60^(@)`

sin^(2)30+cos^(2)60

Show that : cos^(2)60^(@)-sin^(2)60^(@)=-sin30^(@)

Show that : cos^(2)60^(@)-sin^(2)60^(@)=-sin30^(@)

Value of sin60^@//cos60^@

sin30 ^ (@) sin ^ (2) (60) ^ (@) + 3cos60 ^ (@) tan45 ^ (@) =

Find x:sin 2x = sin 60^(@) cos 30^(@) - cos 60^(@) sin 30^(@) .

({(4) / (tan ^ (2) 60 ^ (@)) + (1) / (cos ^ (2) 30 ^ (@)) - 2sin ^ (2) 45 ^ (@)}) / ( (sin ^ (2) 60 ^ (@) + cos ^ (2) 45 ^ (@)))

((4) / (tan ^ (2) 60 ^ (@)) + (1) / (cos ^ (2) 30 ^ (@)) - 2sin ^ (2) 45 ^ (@)) / (sin ^ (2) 60 ^ (@) + cos ^ (2) 45 ^ (@))

((4) / (tan ^ (2) 60 ^ (@)) + (1) / (cos ^ (2) 30 ^ (@)) - 2sin ^ (2) 45 ^ (@)) / (sin ^ (2) 60 ^ (@) + cos ^ (2) 45 ^ (@))

The simplified value of/सरलीकृत मान ज्ञात करें: [(sin^2 25+sin^2 65)/(cos^2 24+ cos^2 66) +sin^2 71+cos71. Sin19 ]
