15 Questions

Quiz Description

This quiz, o level trigonometry quiz is made up of 15 exam based questions which have been set based on the national curriculum for the gce o level, specially made available for you by gcequiz.com.

Trigonometry is a branch in mathematics. This branch deals with the relationships that exist between side lengths and the angles of a triangle using some particular functions known as trigonometric functions (or simply trig functions) which are cosine (cos), sine (sin), secant (sec), tangent (tan), cotangent (cot) or cosecant (cosec).
