Answer:

Step-by-step explanation:

\frac{secx-1}{secx+1}

माना  कि  y=\frac{secx-1}{secx+1}

y=\frac{\frac{1}{cosx} -1}{\frac{1}{cosx} +1} =\frac{1-cosx}{1+cosx}

∴ अवकलन करने पर -

\frac{dy}{dx} =\frac{d}{dx} [\frac{1-cosx}{1+cosx}]\\\\\frac{dy}{dx}=\frac{(1+cosx)\frac{d}{dx}(1-cosx)-(1-cosx)\frac{d}{dx}(1+cosx)}{(1+cosx)^2}\\\\\frac{dy}{dx}=\frac{(1+cosx)(sinx)-(1-cosx)(-sinx)}{(1+cosx)^2}\\\\\frac{dy}{dx}=\frac{sinx+sinxcosx+sinx-sinxcosx}{(1+cosx)^2}\\\\\frac{dy}{dx}=\frac{2sinx}{(1+cosx)^2}
