To help solve the trigonometric inequality
WebbSolving basic trig inequalities proceeds by using trig conversion tables (or calculators), then by considering the various positions of the variable arc x that rotates on the trig … WebbTrigonometry. Trigonometry (from Ancient Greek τρίγωνον (trígōnon) 'triangle', and μέτρον (métron) 'measure') is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies.

WebbStep 1. In mathematics, Inequality means the value which is not equal. Although, there are also some symbols in mathematics that describe the Inequality of any number. So, the first step of solving trigonometric Inequalities is to convert the inequality sign into equality.
Webb8 juli 2016 · So for your expression to be greater than $1$, is suffices to check in which intervals $$\left \sin y \right > \frac{1}{\sqrt{2}}$$ where $y = x + \frac{\pi}{4}$. This is not hard to do by looking at a graph of $\sin y$, remembering that $\sin y = \frac{1}{\sqrt{2}} \iff y = 2\pi k + \frac{\pi}{4}$ or $y = 2\pi k + \frac{3\pi}{4}$.
