The values of trigonometric numbers can be derived through a combination of methods. The values of sine and cosine of 30, 45, and 60 degrees are derived by analysis of the 30-60-90 and 90-45-45 triangles. If the angle is expressed in radians as , this takes care of the case where a is 1 and b is 2, 3, 4, or 6. If the denominator, b, is multiplied by additional factors of 2, the sine and cosine can be derived … WebExplanation: To find the exact values of the sine, cosine, and tangent of -13π/12, we first need to determine its reference angle, which is the acute angle between the terminal side of the angle and the x-axis. To do this, we add 2π radians (or 360 degrees) to -13π/12 until we get an angle between 0 and 2π radians: personal property tax receipt st charles mo
