Question

 The number of solutions of the equation 2x+3tanx=π,x[2π,2π]{±π2,±3π2} is: \text { The number of solutions of the equation } 2 x+3 \tan x=\pi, x \in[-2 \pi, 2 \pi]-\left\{ \pm \frac{\pi}{2}, \pm \frac{3 \pi}{2}\right\} \text { is: }

Options

Solution

2x+3tanx=πtanx=π2x3,x[2π,2π]{±π2,±3π2}\begin{aligned} & 2 x+3 \tan x=\pi \\ & \Rightarrow \quad \tan x=\frac{\pi-2 x}{3}, x \in[-2 \pi, 2 \pi]-\left\{ \pm \frac{\pi}{2}, \pm \frac{3 \pi}{2}\right\} \end{aligned} 5 solutions
