WebThe 6 trigonometric functions are Sine, Cosine, Tangent, Cosecant, Secant, and Cotangent. The phrase “Soh-Cah-Toa” is used to determine which function to use. The functions are used to find unknown angles or distances on geometric figures. Trigonometry is important because it is used in many real-life situations. For example, building houses, radar … Web10.5. =. 0.79. To graph the sine function, we mark the angle along the horizontal x axis, and for each angle, we put the sine of that angle on the vertical y-axis. The result, as seen above, is a smooth curve that varies from +1 to -1. Curves that follow this shape are called 'sinusoidal' after the name of the sine function. http://www.math.com/tables/trig/identities.htm honey gorou
