WebThe expression sin (5x-3y) means that you are taking the sine function of (5x-3y), That is not a multiplication and you certainly don't use the distributive property. Thus, sin (kx) is NOT sine times kx. sin (kx) = 1/2 {ie^ (-kxi)- ie^ (kxi)} Instead, you treat sin (5x-3y) as a … WebNov 10, 2016 · How do you find the derivative of sin(x + y) = xy?

WebAnswer: The derivative of sin (log x) is [cos (log x)] / [x ln 10]. Example 2: Find the derivative of sin x cos x using the formula of derivative of sin x. Solution: Let y = sin x … WebThe derivative of sin x is denoted by d/dx (sin x) = cos x. The other way to represent the sine function is (sin x)’ = cos x. (d/dx) sin x = cos x The derivative of sin x can be found using three different methods, such as: By using the chain rule By using the quotient rule By using the first principle. how do you defeat the cloudburst tank
