INNER JOIN wp_posts as p ON pm.post_id = p.IDĪND p.post_status = 'publish' AND (pm.meta_value LIKE '%"basic-global"%' OR pm.meta_value LIKE '%"basic-singulars"%' OR pm.meta_value LIKE '%"page|all"%' OR pm.meta_value LIKE '%"post-1068"%') ORDER BY p. Here is the Trig portion of my Algebra/Trig Review. This can be simplified to: ( a c )2 + ( b c )2 1. SELECT p.ID, p.post_name, pm.meta_value FROM wp_postmeta as pm For the next trigonometric identities we start with Pythagoras Theorem: The Pythagorean Theorem says that, in a right triangle, the square of a plus the square of b is equal to the square of c: a 2 + b 2 c 2.
