Nếu sin x = 0, hãy tính giá trị của (1 + cos x) / cos^2 (x/2) (nếu xác định).

Find the derivative of sin x at x = 0. Let f(x) = sin x. We know that f'(x) = (lim)┬(h→0) f⁡〖(x + h) − f(x)〗/ Since x0 was arbitrarily chosen hence the function f(x) is continuous in R. Each fk(x) = sin(x/k) k is differentiable with. = sinx + sinx · 1 = 2 sinx. Now, f2(x) = sinx + R π/2. 0 sinxcosy · f1( ... What is x(1), x(2), x(10), x(0)?.
