WebJun 14, 2024 · We know that cos t is the x -coordinate of the corresponding point on the unit circle and sin t is the y -coordinate of the corresponding point on the unit circle. So: x = cos t = 1 2 y = sin t = √3 2. Try It 2.2.1. A certain angle t corresponds to a point on the unit circle at ( − √2 2, √2 2) as shown in Figure 2.2.5. WebNov 2, 2024 · Quadrants of trigonometry QUADRANTS What is the exact value of csc 225 ° ? Solution: Here cosec is positive only in 1st and 2nd Quadrant. 225° does not lies in 1st and 2nd Quadrant. cosec is negative in 3rd Quadrant. Therefore cosec (180° + θ) = – cosec θ 225° lies in 3rd Quadrant. cosec (225°) = cosec (180° + 45°) cosec (225°) = – cosec (45°)
WebFeb 2, 2024 · Generally, trigonometric functions (sine, cosine, tangent, cotangent) give the same value for both an angle and its reference angle. The only thing that changes is the … Websin stands for sine.cos stands for cosine. cosine is the co-function of sine, which is why it is called that way (there's a 'co' written in front of 'sine').Co-functions have the relationship …
