Step-by-step explanation:
Answer:
![y = e^{3x}.cos4x.sin2x](https://tex.z-dn.net/?f=y%20%3D%20e%5E%7B3x%7D.cos4x.sin2x)
![=> y' =- 3e^{3x}.4sin4x.2cos2x=-24.e^{3x}.sin4x.cos2x](https://tex.z-dn.net/?f=%3D%3E%20y%27%20%3D-%203e%5E%7B3x%7D.4sin4x.2cos2x%3D-24.e%5E%7B3x%7D.sin4x.cos2x)
![dy=y'.dx => dy = -24e^{3x}.sin4x.cos2x.dx](https://tex.z-dn.net/?f=dy%3Dy%27.dx%20%3D%3E%20dy%20%3D%20-24e%5E%7B3x%7D.sin4x.cos2x.dx)
Step-by-step explanation:
Answer: Add like terms
Step-by-step explanation:
For example, you would add 6x and 5x to make 11x, but there other two numbers you would leave alone.
