Impara online a risolvere i problemi di passo dopo passo. sin(x+pi/2)-sin(x-pi/2)=1. Applicare la formula: a=b\to a\sin\left(\theta \right)=b\sin\left(\theta \right), dove a=\sin\left(x+\frac{\pi }{2}\right)-\sin\left(x-\frac{\pi }{2}\right) e b=1. Applicare la formula: 1x=x, dove x=\sin\left(x\right). Applicare la formula: a=b\to a-b=0, dove a=\sin\left(x\right)\left(\sin\left(x+\frac{\pi }{2}\right)-\sin\left(x-\frac{\pi }{2}\right)\right) e b=\sin\left(x\right). Applicare la formula: ax+bx=x\left(a+b\right), dove a=\sin\left(x+\frac{\pi }{2}\right)-\sin\left(x-\frac{\pi }{2}\right), b=-1 e x=\sin\left(x\right).

sin(x+pi/2)-sin(x-pi/2)=1
