Question

Let a, b and c be real numbers and a must be different from 0.

Prove that at least one of the following equations has real solutions.$a sinx+b cosx+c=0,\\a tgy+b ctgy+2c=0$

Answer 1

Step-by-step explanation:

Let a, b and c be real numbers and a must be different from 0.

Prove that at least one of the following equations has real solutions.\begin{gathered}a sinx+b cosx+c=0,\\a tgy+b ctgy+2c=0\end{gathered}

asinx+bcosx+c=0,

atgy+bctgy+2c=0
