सोडोवचें d/dx(ln(tanh(1/x)))

$$\frac { d } { d x } ( \ln ( \tanh ( \frac { 1 } { x } ) ) )$$

मूल्यांकन करचें

$$-\frac{\left(\frac{\operatorname{sech}(\frac{1}{x})}{x}\right)^{2}}{\tanh(\frac{1}{x})}$$

w.r.t. x चो फरक काडचो

$$\frac{\left(2x\tanh(\frac{1}{x})-2\left(\tanh(\frac{1}{x})\right)^{2}-\left(\operatorname{sech}(\frac{1}{x})\right)^{2}\right)\times \left(\frac{\operatorname{sech}(\frac{1}{x})}{\tanh(\frac{1}{x})}\right)^{2}}{x^{4}}$$
