WebDerivative of cos 2x is -2 sin 2x which is the process of differentiation of the trigonometric function cos 2x w.r.t. angle x. It gives the rate of change in cos 2x with respect to angle x. The derivative of cos 2x can be derived using different methods. Mathematically, the derivative of cos 2x is written as d(cos 2x)/dx = (cos 2x)' = -2sin 2x. WebAnswer: the derivative of cos (x)sin (x) = cos2(x) − sin2(x) Why Does It Work? When we multiply two functions f (x) and g (x) the result is the area fg: The derivative is the rate of change, and when x changes a little then both f and g will also change a little (by Δf and Δg). In this example they both increase making the area bigger.

Webe^x times 1. f' (x)= e^ x : this proves that the derivative (general slope formula) of f (x)= e^x is e^x, which is the function itself. In other words, for every point on the graph of f (x)=e^x, the slope of the tangent is equal to the y-value of tangent point. So if y= 2, slope will be 2. if y= 2.12345, slope will be 2.12345.
