Apply the trigonometric identity: \frac{d}{dx}\left(\mathrm{tanh}\left(\theta \right)\right)=\mathrm{sech}\left(\theta \right)^2\frac{d}{dx}\left(\theta \right), where x=\frac{y}{x}. Apply the formula: \frac{d}{dx}\left(\frac{a}{b}\right)=\frac{\frac{d}{dx}\left(a\right)b-a\frac{d}{dx}\left(b\right)}{b^2}, where a=y and b=x. Apply the formula: \frac{d}{dx}\left(c\right)=0, where c=y. Apply the formula: x+0=x, where x=-y\frac{d}{dx}\left(x\right).
