中文 这是一个函数图像绘制程序，它可以绘制y=1至9x、y=1至9+x、y=1至9/x、 y=1至9-x、y=1至9平方根x、sin函数、cos函数、tan函数、自然对数ln函数和对数log函数 示例：y=cos x English This is a function graph printing program. It can print y=1 to 9x, y=1 to 9+x, y=1 to 9/x, y=1 to 9-x, y=1 to 9 square root x, sin function, cos function, tan function, natural logarithm ln function and logarithmic log function Example: y=cos x
