Trigonometric functions of 30 degrees
WebJun 25, 2015 · The trigonometric ratios for 30^o, 45^o, and 60^o are based on some standard triangles. sin, cos, and tan (and their reciprocals) are the ratios of the sides of these triangles. Both 30^o and 60^o are based on an equilateral triangle with sides of length 2 and with one of the angles bisected. The 45^o angle is based on an isosceles triangle … WebWith your palm facing you, count off the basic reference angles, starting with your thumb: 0°, 30°, 45°, 60°, and 90°. To find a trig value, you'll lower the finger corresponding to that angle, keeping your palm facing you. For the sine value, you'll take the square root of the number of fingers to the left of the lowered finger, and ...
