WebFind the value of given trigonometric ratio. Given trigonometric ratio: sin 75 ∘ sin 75 ∘ can be expressed as, sin 75 ∘ = sin ( 45 ∘ + 30 ∘) We know that sin ( A + B) = sin A cos B + cos A sin B So by applying the above formula we get, sin 75 ∘ = sin 45 ∘ cos 30 ∘ + cos 45 ∘ sin 30 ∘ Web已知cos2阿尔法=3分之根号2,则sin阿尔法的四次方+cos阿尔法的四次方的值为?
