Giải phương trình sin x + cos x = √2 sin x và xác định các nghiệm thỏa mãn sin x = 0.

Again, before starting this problem, we note that the Taylor series expansion at x = 0 is equal to the Maclaurin series expansion. Step 1: Find Coefficients. f(x) = sin x ∙ cos x. Example 3. Solve the equation sin x ∙ cos x − sinx = 0 and then the inequality sin x ∙ cos x − sin x > 0 on the interval 0 x < 2 . Nov 6, 2022 ... Show that near x=0,sinx≈x,cosx≈1, and tanx≈x. 5.
