By using a right-angled triangle as a reference, the trigonometric functions and identities are derived: sin θ = Opposite Side/Hypotenuse. Differentiate the function with respect to x: xsinx +(sinx)cosx. Often, if the argument is simple enough, the function value will be written without parentheses, as sin θ rather than as sin(θ). cos2x = 1 2 + 1 2cos(2x) = 1 + cos(2x) 2. sin (2x) = 2 sin x cos x. and. Which is the product of two functions, and so we apply the Product Rule for Differentiation: d dx (uv) = u dv dx + du dx v, or, (uv)' = (du)v +u(dv) I was taught to remember the rule in words; " The first times the derivative of the second plus the derivative of the first times the second ". 2 - The cosine laws.664, 3.stsop golb balobmyS detaleR .
