fog和平行曲线建立参数曲线的疑问
想要画出如下参数方程对应的曲线t∈
y=150.74506251035174386743165086955*exp(-0.000025841221730389136711832006913315*t**2) - 150.74506251035174386743165086955
形状本应为(蓝线)
我用catia 画时,参考直线为453.3长度的水平直线,参数方程中将t替换为 t*453.3, 画出曲线为
十分不解,向大佬求助!
已解决;
公式应由
y=150.74506251035174386743165086955*exp(-0.000025841221730389136711832006913315*t**2) - 150.74506251035174386743165086955
变为
y=150.74506251035174386743165086955*exp(-0.000025841221730389136711832006913315*(t*453.3)**2) - 150.74506251035174386743165086955
而非
y=150.74506251035174386743165086955*exp(-0.000025841221730389136711832006913315*t*453.3**2) - 150.74506251035174386743165086955
或
y=150.74506251035174386743165086955*exp(-0.000025841221730389136711832006913315*453.3*t**2) - 150.74506251035174386743165086955
厉害厉害 高手 完全用不懂这个 学习一下,以后用得着的
