To solve a trigonometric inequation of the type sin x ≥ a where |a| ≤ 1, we take a hill of length 2 in the sine curve and write the solution within that hill. For the general solution, we add 2n
. For instance, to solve
, we take the hill
over which solution is
The general solution is
, n is any integer. Again to solve an inequation of the type sin x ≤ a, where |a| ≤ 1, we take a hollow of length 2
in the sine curve. (since on a hill, sinx ≤ a is satisfied over two intervals). Similarly cos x ≥ a or cosx ≤a, |a| ≤ 1 are solved.
Solution to the inequation must be
