Trigonometry Cast Diagrams And Solving Equations Youtube Here i show you how to use the quadrant rule or cast diagram to solve trigonometric equations in different ranges. it saves having to use trigonometric graph. The cast diagram helps us to remember the signs of the trigonometric functions in each of the quadrants. the cast diagram is also called the quadrant rule or the astc diagram. in the first quadrant, the values are all positive. in the second quadrant, only the values for sin are positive. Tanx = √3. for x = 60°, tanx = √3. draw this angle from the horizontal x axis, in an anticlockwise direction. draw the same angle from the horizontal axis in the other three quadrants. list out the solutions among the quadrants following the signs determined by the cast diagram. given equation: tanx √3 = 0, so tanx = √3. 2. about the cast diagram to learn about the cast diagram please click on the trigonometry theory guide (hsn) link and read from page 2. please also find in sections 2 & 3 below trig equations videos 1 & 2, mind maps (see under trigonometry) and worksheets on this topic to help your understanding.

What you will learn. in this lesson, we look at the cast diagram in detail and relate its mechanics to the sin and cos graphs directly. this is a very important aspect of trigonometry as this links the equations to the charts and provides a framework from which we can solve and analyse any given equation. A detailed cast diagram is shown below:. a simpler version of the diagram is shown below: . a ⇒ all (sine, tan & cosine) positive 0° – 90° s ⇒ sine positive 90° – 180° t ⇒ tan positive 180° – 270° c ⇒ cosine positive 270° – 360° the cast diagram can also be called a astc diagram as it keeps the letters in the correct.
