Expand out sin 2x, using the double angle formula, you get: 2 sin x cos x. Now multiply through by cos x / cos x, giving: 2 sin x cos^2 x / cos x. Which can be written: 2 (sin x / cos x) * cos^2 x. We know that cos = 1 / sec, so, this can be written: 2 (sin x / cos x) * 1 / sec^2 x. We know sin x / cos x = tan x, and sec^2 = 1 + tan^2, so, we get: Using this general formula, derive the Maclaurin expansion of sin 2x. The sequence of steps is very similar to the sin x derivation that was shown earlier. Since sin 0 = 0, it is the cosine derivatives, which will yield a result.

Simple step by step solution, to learn. Simple, and easy to understand, so don`t hesitate to use it as a solution of your homework. Below you can find the full step by step solution for you problem. We hope it will be very helpful for you and it will help you to understand the solving process. 3 Euler’s formula The central mathematical fact that we are interested in here is generally called \Euler’s formula", and written ei = cos + isin Using equations 2 the real and imaginary parts of this formula are cos = 1 2 (ei + e i ) sin = 1 2i (ei e i ) (which, if you are familiar with hyperbolic functions, explains the name of the In more general terms, sin (2x) = sin (x+x) = cos (x)sin (x)+sin (x)cos (x) = 2sin (x)cos (x), which cannot be equal to 2 sin (x). The derivative of sin2x is 2cos (2x).
