Derivative of cos x/3
Webf' (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 2 comments ( 25 votes) Upvote WebJan 25, 2024 · Theorem 3.3.1: The Derivatives of sin(x) and cos(x) The derivative of the sine function is the cosine and the derivative of the cosine function is the negative sine. d dx(sin(x)) = cos(x) d dx(cos(x)) = − sin(x) Proof Figure 3.3.3 shows the relationship between the graph of f(x) = sinx and its derivative f′(x) = cosx.
