In this paper, we determine new and sharp inequalities involving trigonometric functions. More specifically, a new general result on the lower bound for log(1−uv), u, v ∈ (0, 1) is proved, allowing to determine sharp lower and upper bounds for the so-called sinc function, i.e., sin(x)/x, lower bounds for cos(x) and upper bounds for (cos(x/3)) 3. The obtained bounds improve some well-established results. The findings are supported by graphical analyses
