What are the angles of elevation and depression? a clif is perpendicular to the sea and the top of the clif stands 24 m above the level of the sea. the x angle of depression from the clif to a boat at sea is 35°. at a point m up the clif is a flag marker and. the angle of elevation from the boat to the flag marker is 18°. Consider all four possible angles that can be made from the horizontal axis to each of the lines drawn. the range is 2π ≤ θ ≤ 2π so the angles can be in both the positive and negative direction. the angle in the positive direction to the line in the fourth quadrant is 2 0.6435 = 5.63968. Find everything you need to revise this topic, so you can go into your exam confident and prepared. teachers and examiners write all our resources, and they’re designed specifically for each exam board. we regularly update them to match the latest syllabus, so you’ll only revise the most accurate, up to date information.

This document provides notes on trigonometric concepts for o level students. it explains pythagoras' theorem, trigonometric ratios, supplementary angle rule, sine rule, cosine rule, and other topics. pythagoras' theorem can be used to find the hypotenuse of a right triangle given two other sides. Specialising in o level mathematics maths secrets trigonometry (quadrants) 1 given that sin =− and cos =− , where a and b are in the same quadrant and p and q are positive constants, find the value of (i) sin(− ), (ii) tan(45°− ), (iii) sec(2 ). ans: (i) sin(− )= (ii) tan(45°− )=√1− 2−. Trigonometry proving is a question that test a student’s ability to observe trigonometry relationships, manipulating it until the ˚˜ of the equation is equal to !˜ of the equation. these questions are normally followed by the use of the proof to solve an equation. some considerations when performing trigonometry proving 1. You can solve trig equations in a variety of different ways. sketching a graph (see graphs of trig functions) using trigonometric identities (see simple trig identities and further trig identities) using the cast diagram (see linear trig equations) factorising quadratic trig equations (see quadratic trig equations).
