怎么画椭圆
import turtle

    '''
    a->轴x长度
    b->轴y长度
    steps->椭圆弧度
    rotateAngle->椭圆斜度
    '''
    
    minAngle = (2*math.pi/360) * angle / steps

    rotateAngle = rotateAngle/360*2*math.pi

    turtle.penup()

    turtle.setpos(b*math.sin(rotateAngle),-b*math.cos(rotateAngle))

    turtle.pendown()

    for i in range(steps):

        nextPoint = [a*math.sin((i+1)*minAngle),-b*math.cos((i+1)*minAngle)]

        nextPoint = [nextPoint[0]*math.cos(rotateAngle)-nextPoint[1]*math.sin(rotateAngle),

                     nextPoint[0]*math.sin(rotateAngle)+nextPoint[1]*math.cos(rotateAngle)]

        turtle.setpos(nextPoint)
