WebAnswer (1 of 6): The other answers are good, but here’s another idea, assuming you have a calculator. Find the sine and cosine of the angle (make sure your calculator is in radian …
Determine the quadrant that the angle and triangle lies in
WebA Quadrantal Angle is an angle in standard position with terminal side on the x-axis or y-axis. Some examples are the angles located at 0°, 90°, 180°, 270°, 360°, 450°, ... as well as -90°, -180°, -270°, -360°. If the three basis … WebUsing a similar approach, we can find the six trigonometric functional values for. θ = π/2, θ = π, and θ = 3π/2 as, The trigonometric functional values of angles coterminal with 0, π/2 , π, and 3π/2 are the same as those above, and the trigonometric functional values repeat themselves (e.g., π and 3π are coterminal and sin (π) = sin ... included warranty

WebFor example, if the angle is 215°, then the reference angle is 215° – 180° = 35°. The reference angle if the terminal side is in the fourth quadrant (270° to 360°) is (360° – given angle). An angle of 330°, for example, can be referred to as 360° – 330° = 30°. Example for Finding Coterminal Angles and Classifying by Quadrant WebThe phrase "$\sin \theta = 4/5$ is in the second quadrant" is malformed. It is a splice of two ideas: "$\sin \theta = 4/5$" and "$\theta$ is in the second quadrant". It is indicative of confusion to say that the side length ratio $\frac{4}{5}$ is in any quadrant. Since $\theta$ is in the second quadrant, $\dfrac{\pi}{2} < \theta < \pi$. WebValues of Quadrantal Angles. When an angle lies along an axis, the values of the trigonometric functions are either 0, 1, -1, or undefined. When the value of a trigonometric function is undefined, it means that the ratio for that given function involved division by zero. Below is a table with the values of the functions for quadrantal angles. included with fare traduzione
