Our Co function identity for secant Theta is that secant Theta equals cosecant of 90° minus Theta. This is an identity. This is a formula we need to know. So secant of 52° equals cosecant of 90° -, 52° secant of 52 is just equal to cosecant of 38°. If we thought about putting this in a triangle aspect, we would know that if we have this being 52°, the secant being the hypotenuse over the adjacent side, then if we looked at 38°, this is the complementary angle. The cosecant of this would be the hypotenuse over the opposite or H / A again.
