Answer:

Step-by-step explanation:

\dfrac{\sin (x + a)}{\cos x}

माना कि   y=\dfrac{\sin (x + a)}{\cos x}

∴ अवकलन करने पर -

\frac{dy}{dx}  =\frac{d}{dx} \dfrac{\sin (x + a)}{\cos x}\\\\=\frac{cosx\frac{d}{dx}[sin(x+a)]-[sin(x+a)]\frac{d}{dx} cosx }{(cosx)^2} \\\\=\frac{cosx.cos(x+a)-sin(x+a)(-sinx)}{(cosx)^2}\\ \\=\frac{cosx.cos(x+a)+sin(x+a)sinx}{cos^2x} \\\\=\frac{cos(x+a-x)}{cos^2x}\\ \\=\frac{cosa}{cos^2x}

\frac{dy}{dx} =\frac{cosa}{cos^2x}
