**How do you determine the exact value of a trigonometric**

www.justmaths.co.uk Version 2 November 2015 Exact Value of Trigonometric Ratios A collection of 9-1 Maths GCSE Sample and Specimen questions from AQA, OCR, Pearson-Edexcel and WJEC Eduqas.... In the module, Further Trigonometry, we saw how to use points on the unit circle to extend the definition of the trigonometric ratios to include obtuse angles. That same construction can be extended to angles between 180Â° and 360Â° and beyond. The sine, cosine and tangent of â€¦

**How do you determine the exact value of a trigonometric**

Since the trigonometric ratios of 3 0 âˆ˜ 30^\circ 3 0 âˆ˜ are defined to be the ratios of the sides of a right triangle with a 3 0 âˆ˜ 30^\circ 3 0 âˆ˜ angle, we can start by drawing and labeling the sides of a 3 0 30 3 0 - 6 0 60 6 0 - 9 0 90 9 0 triangle.... To evaluate the six trigonometric functions of 225 degrees using the unit circle, follow these steps: The sine of an angle is the y value, or the vertical line that extends from the point on the unit circle to the x-axis. For 225 degrees, the y value is. Find the cosine of the angle. The cosine value is the x value, so it must be . Find the tangent of the angle. To find the tangent of an

- How to calculate exact value of a trig function? Ask Question 2. 1. I am writing a "triangle solver" app for Android, and I was wondering if it would be possible to implement exact values for trig ratios and radian measures. For example, 90 degrees would be output as "pi / 2" instead of 1.57079632679... I know that in order to get the exact value for a radian measure, I would divide it by pi
