Impara online a risolvere i problemi di passo dopo passo. -*2^(1/2)csc(a)^2-2csc(a)=0. Applying the trigonometric identity: \csc\left(\theta \right)^2 = 1+\cot\left(\theta \right)^2. Applicare la formula: -\left(a+b\right)=-a-b, dove a=1, b=\cot\left(a\right)^2, -1.0=-1 e a+b=1+\cot\left(a\right)^2. Applicare la formula: x+a=b\to x=b-a, dove a=-2\csc\left(a\right), b=0, x+a=b=\sqrt{2}\left(-1-\cot\left(a\right)^2\right)-2\csc\left(a\right)=0, x=\sqrt{2}\left(-1-\cot\left(a\right)^2\right) e x+a=\sqrt{2}\left(-1-\cot\left(a\right)^2\right)-2\csc\left(a\right). Applicare la formula: x+ax=x\left(1+a\right), dove a=\cot\left(a\right)^2 e x=-1.
