The Derivative of sinx at x=0 By definition, the derivative of sinx evaluated at x = 0 is lim h→0 sinh− sin0 h = lim h→0 sinh h The figure below contains a circle of radius 1. Recall that an arc of length h on such a circle subtends an angle of h radiansat the center of the circle. So the darkened arc in the figure

derivative is +cos(x). On the other hand, just after x = 0, cos(x) is decreasing, and sin(x) is positive, so the derivative must be −sin(x). Example 1 Find all derivatives of sin(x). Solution Since we know cos(x) is the derivative of sin(x), if we can complete the above task, then we will also have all derivatives of cos(x). d dx sin(x) = cos(x)

Derivative of sin Recall that in Example 31(c) we guessed that d dx sinx = cosx by considering the graphs of sin and cos. We will now prove this using the denition of the derivative and some basic trigonometric identities. First recall the sum and difference formulas for sin sin(x y) Though we don’t need it right away, the corresponding ...

2. When taking the derivative of any term that has a “y” in it multiply the term by y0 (or dy=dx) 3. Solve for y0 When finding the second derivative y00, remember to replace any y0 terms in your final answer with the equation for y 0you already found. In other words, your final answer should not have any y terms in it. 2
