Sketching the situation before solving
Sketching the situation before solving means drawing a simple labelled diagram before writing any trigonometric equation.
Practice This ConceptMain explanation
Teacher explanation
A good sketch is the first tool in application questions. It helps you identify the observer, object, horizontal line, vertical height, and line of sight. Once the sketch is ready, the correct angle and trigonometric ratio become much easier to spot. Many students lose marks because they start with formulas and only later try to imagine the diagram. In this chapter, sketching is not optional; it is part of the solution method.
Example
For a building problem, a sketch shows the building vertical, the ground horizontal, and the viewer's line of sight slanting upward.
Simple analogy
Sketch first, solve second.
Common confusion
Students often skip the sketch and then mix up the sides or the angle position.
Exam tip
A neat sketch can save marks even if arithmetic is slightly weak, because it shows the correct mathematical setup.
