WebWe calculate the trigonometric functions sine, cosine, and tangent using a unit circle. From the image, we can calculate trigonometric values for any angle. sinθ = Opposite / Hypotenuse = y / 1 sinθ = y, sine is y-coordinate cosθ = Adjacent / Hypotenuse = x / 1 cosθ = x, cosine is x-coordinate tanθ = Opposite / Adjacent = y / x tanθ = y / x Websine (theta) = y/r → y = r * sine (theta) cosine (theta) = x/r → x = r * cosine (theta) For example, if r is 75 and theta is 45 degrees (or PI/4 radians), we can calculate x and y as below. The functions for sine and cosine in ProcessingJS are sin () and cos (), respectively. They each take one argument, an angle measured in degrees. エフワングランプリWebThe distance from the origin to where that tangent line intercepts the y-axis is the cosecant (CSC). The sign of that value equals the direction positive or negative along the y-axis you need to travel from the origin to that y-axis intercept. Some people can visualize what happens to the tangent as the angle increases in value. エフワン
