Impara online a risolvere i problemi di passo dopo passo. sin(t)^4-cos(t)^4=sin(t)^2-cos(t)^2. Partendo dal lato sinistro (LHS) dell'identità. Simplify \sqrt{\sin\left(\theta\right)^4} using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 4 and n equals \frac{1}{2}. Applicare la formula: 1x=x, dove x=\cos\left(\theta\right)^4. Simplify \sqrt{\cos\left(\theta\right)^4} using the power of a power property: \left(a^m\right)^n=a^{m\cdot n}. In the expression, m equals 4 and n equals \frac{1}{2}.

sin(t)^4-cos(t)^4=sin(t)^2-cos(t)^2
