Cast Diagram Radians. Trigonometric equations can be solved in degrees or radians using cast and its period to find other solutions within the range including multiple or compound angles and the wave function. In the first quadrant the values are all positive.
Stands for cosine all sine tan. The cast diagram helps us to remember the signs of the trigonometric functions in each of the quadrants. Here i show you how to use the quadrant rule or cast diagram to solve trigonometric equations in different ranges.
Stands for cosine all sine tan.
The cast diagram is also called the quadrant rule or the astc diagram. The cast diagrams for the tangent function are simpler in form than the others you merely add multiples of 180 to obtain all the solutions needed. Because we want answers between 0 and 2π we correct θ pv by adding 2π to get 4 97 and state. The symmetry of the diagram gives θ 2 1 313 π 1 828 radians.
