26 de ago. de 2023 · To find where u = log(x + y + z) and x = cos t , y = sin² t , and z = cos² t , we will use the chain rule along with the derivatives of the trigonometric functions. Given: u = log(x + y + z) x = cos t . y = sin² t . z = cos² t . We have: We'll differentiate u with respect to t : Now, let's substitute the expressions for x , y , and z : So,

16 de jul. de 2021 · The radius of curvature of a curve is a measure of how sharply the curve is bent at a certain point. To find the radius of curvature of the curve x = t^2 and y = t at t = 1, we can use the following formula: where R is the radius of curvature, x' and y' are the first derivatives of x and y with respect to t, and x'' and y'' are the second ...
默认排序. ZizhouH. 关注计算机图形学，物理仿真. 如果不满足这个就无法讨论曲线的切向以及更多很好的性质，所以需要这个假设。. 发布于 2020-01-26 20:59. 095781. 这个意思是弧长函数连续. 发布于 2021-01-11 06:02. 例如x (t)=t⁵,y (t)=t³怎么就不是光滑曲线了?
