WebIf you know that the derivative of sine of x with respect to x is cosine of x and the derivative of cosine of x with respect to x is negative sine of x, that can empower you to do many more, far more complicated derivatives. … WebWhy is the derivative of Cos negative? At x = 0, sin(x) is increasing, and cos(x) is positive, so it makes sense that the derivative is a positive cos(x). On the other hand, just after x = 0, cos(x) is decreasing, and sin(x) is positive, so the derivative must be a negative sin(x).

WebApr 15, 2016 · 1 Answer Jim H Apr 15, 2016 1 √1 −x2 Explanation: 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 .)
