什么是(-3pi)/ 4弧度(度)?
颜色(栗色)(= -135 ^ @ = 225 ^ - (3pi)/ 4 =>(((( - 3pi)/ 4)* 180)/ pi)^ @ => - ((3取消(pi) *取消(180)^颜色(红色)(45))/(取消(4)*取消(pi)))=> -135 = 360 - 135 = 225 ^ @
什么是(7pi)/ 4弧度(以度为单位)?
颜色(白色)(xx)315color(白色)(x)“度”颜色(白色)(xx)1color(白色)(x)“弧度”= 180 / picolor(白色)(x)“度”=>( 7pi)/ 4color(白色)(x)“弧度”=(7pi)/ 4 * 180 / picolor(白色)(x)“度”颜色(白色)(xxxxxxxxxx)= 315color(白色)(x)“度”
