We often use this function when designing the die position to calculate the angle of the shovel seat. There is also the angle of the product when making the mold, such as the product slope around 1, the height of 10MM, and how big the horizontal drop will be. Lao shifu can work it out at once, because he remembers the drop of11mm. Think about these functions at that time. High school mathematics scared him. Sine and cosine tangent cotangent, but now it's okay. I'm just kidding you. There are so complicated things in life, leaving the simplest angle travel calculation and function. . floating clouds
