Question

(d) $\frac{a}{{\sqrt {{a^2} + {b^2}} }}\sin x + \frac{b}{{\sqrt {{a^2} + {b^2}} }}\cos x = \frac{c}{{\sqrt {{a^2} + {b^2}} }}$

$\sin (x + \alpha )

None of these

Vedclass · Answer

(d) $\frac{a}{{\sqrt {{a^2} + {b^2}} }}\sin x + \frac{b}{{\sqrt {{a^2} + {b^2}} }}\cos x = \frac{c}{{\sqrt {{a^2} + {b^2}} }}$

$\sin (x + \alpha ) = \frac{c}{{\sqrt {{a^2} + {b^2}} }} > 1$, (as given)

Hence there is no solution.

The number of solution of the given equation $a\sin x + b\cos x = c$ , where $|c|\, > \,\sqrt {{a^2} + {b^2}} ,$ is
