3、三角函数的图像可能比较困难,需要在教学时加以指导和突破。正弦函数和余弦函数的图像在三角函数的研究中是一个基础和前提,为后面得出正弦函数和余弦函数的性质、进一步加深对函数图像的研究将起着至关重要的作用。二教学目标设计1、能结合单位圆中的正弦线、余弦线理解正弦函数及余弦函数中函数值的变化规律;2、通过五点法能正确作出正弦函数的图像,并能归纳正弦函数图像的特征;3、通过函数图像的变换,能作出余弦函数及相关函数图像;4、在渗透数形结合的数学思想过程中,培养学生类比和转化的思维习惯。三教学重点难点正弦函数和余弦函数的图像的形成和应用。四教学用具准备多媒体设备五教学流程设计文档编码:CB5U8Z10I8P
