3.　　简单编程题：写一个程序，它在0°和90°之间每隔15°输出一行数据，打印一个表。每行中包括5个项目：角度数，以及它所对应的正弦、余弦、正切、余切函数值(注意角度与弧度间的转换)。-3 simple programming problem: Write a program that between 0 and 90 every 15 line of output data, print a table. Each row consists of five items: the number of angles, and it corresponds to the sine, cosine, tangent, cotangent function value (angle in radians between note conversion).
