WebNov 4, 2024 · Proof of x derivative formula by first principle To prove the derivative of e by using first principle, replace f (x) by x or you can replace it by ln x to find ln derivative. f (x) = lim h→0 f (x + h) - f (x) / h f (x) = lim (x + h) - x / h Moreover, f (x) = lim h / h When h approaches to zero, f (x) = 1 WebApr 15, 2016 · Let y = sin−1x, so siny = x and − π 2 ≤ y ≤ π 2 (by the definition of inverse sine). Now differentiate implicitly: cosy dy dx = 1, so. dy dx = 1 cosy. Because − π 2 ≤ y ≤ π 2, we know that cosy is positive. So we get: dy dx = 1 √1 − sin2y = 1 √1 − x2. (Recall from above siny = x .)
