WebOriginally Answered: How can I differentiate from the first principle cos x^2? Recall from the definition of a derivative [math]f' (x) = \lim_ {h \to 0} \dfrac {f (x + h) - f (x)} {h} [/math]. Here, [math]f (x) = \cos {x^2} [/math]. Now, we have [math]f' (x) = \lim_ {h \to 0} \dfrac {\cos { (x+h)^2} - \cos {x^2}} {h} [/math] WebMar 12, 2024 · 以下是一个简单的 Python 代码示例： ```python import math def derivative(x): return 1 - 2 + 5 * math.cos(x) * math.log(3) x = 1.0 # 在x=1处求导数 dy_dx = derivative(x) print("dy/dx =", dy_dx) ``` 输出结果为： ``` dy/dx = 2.383348218399397 ``` 因此，当 x = 1 时，y=x-2x+5sin(x)ln(3)的导数为2.3833。 ... lee cliff hall
