It satisfies the Pythagorean theorem. b) Evaluate the following: sin 2θ = 16 25 cos 2θ = 9 25 sin 2θ + cos 2θ = 1. Example 2. how does replace work in pythonWebsin (x2) is made up of sin () and x2: f (g) = sin (g) g (x) = x 2 The Chain Rule says: the derivative of f (g (x)) = f' (g (x))g' (x) The individual derivatives are: f' (g) = cos (g) g' (x) = 2x So: d dx sin (x 2) = cos (g (x)) (2x) = 2x cos (x 2) Another way of writing the Chain Rule is: dy dx = dy du du dx photo printed socks wholesale

"WebI think of this as square (sin (x)), that is, a square function of a sine function of x. Think of y = 2x² + 3x as y = f (x) + g (x) where f (x) is 2x² and g (x) is 3x. The functions of x are not being composed/chained as above (so the chain rule doesn't apply), and they are not being multiplied (so the product rule doesn't apply). " - Deriving sin squared
