$\sec (x) = \sin (\frac{1}{2} x)$

Step 1

Combine $\frac{1}{2}$ and $x$ .

$\sec (x) = \sin (\frac{x}{2})$

Step 2

Graph each side of the equation. The solution is the x-value of the point of intersection.

$x \approx - 40.84070449, - 28.27433388, - 15.70796326, - 3.14159265, 9.42477796, 21.99114857, 34.55751919, 47.1238898$
