观看动画演示微积分问题的逐步求解（导数、积分、极限）。
marcushuang4595 · V2EX
做了一个会把微积分解题过程“动起来”的计算器，想听听大家的意见 最近做了一个微积分学习工具 CalculusMate 。 起因是我发现很多计算器只给最终答案，即使列出步骤，也很难看出表达式究竟是怎样一步步变化的。所以我尝试把求导、积分和极限的计算过程做成可以逐步播放的形式。 目前支持： - 导数、积分和极限计算 - 展示每一步使用的规则 - 动画演示表达式的变化 - 支持常见数学符号键盘 - 中英文界面 - 基础计算无需注册 可以从这个页面体验： https://calculusmate.com/step-by-step 免费版本： https://calculusmate.com/free 目前还处于早期阶段，我比较想知道： 1. 解题步骤是否足够容易理解？ 2. 动画是帮助理解，还是会让页面显得太复杂？ 3. 还希望优先支持哪些题型？ 欢迎直接指出问题，尤其是计算结果、移动端体验和表达不清楚的地方。

统一追踪来自54个AI提供商的API成本。
u/No_Entrance772 · Reddit
I nearly cut my free plan retention out of fear. I measured first, and the change did nothing. Backstory first, because that's the honest order. I pay for OpenAI, Anthropic and Cursor. Every one has its own dashboard, none of them agree with each other, and none agree with the invoice. What I actually wanted was boring: what did this feature cost last month, and which customers are expensive to serve. No provider console answers that, because they bill by organisation and API key, not by my

对比 450+ LLM API 模型定价，计算包含缓存和批处理的月度成本。
u/Greywolff06 · Reddit
I built LLMPrice — a free calculator for comparing LLM API costs across 450+ pricing routes I kept running into the same problem when comparing LLM APIs: the headline token price doesn't always tell you what your actual workload will cost. Caching, batch pricing, reasoning tokens, retries, different endpoints, and OpenRouter routes can change the result quite a bit. So I built LLMPrice.com. You enter your workload once — requests, input/output tokens, caching, retries, etc. — and it com
