-is the first one, f^1(x)=5.sin3x-(5x-3).3cos3x/3cos3x.3cos3x ??
-is the second one, 75x^2 - 20x (5x^3-2x^2)^4??

[delicate vessel]

Are you talking about derivatives?

[delicate vessel]

So the first derivative is almost right. The denominator should be only (sin3x)²

[prisma locust]

yes

[delicate vessel]

The second is also almsot correct

[prisma locust]

ohh okayy and do i simplify it?? or is that the final answer?

[delicate vessel]

And dont forget brackets

f'(x) = 5 • (15x² - 4x) • (5x³ - 2x²)⁴

= (75x² - 20x) • (5x³ - 2x²)⁴

[prisma locust]

ohhh i see

[delicate vessel]

Yeah mb

But the brackets are only missing

But otherwisr well done

You can sinplfy depends on the teacher but most of the time no, except if you need the 2n derivative too then it would be helpful

[prisma locust]

is this the final answer? so i dont need to multiply it?

[prisma locust]

thank youu

[delicate vessel]

You can but imo it's enough

Depends as I said what the task giver expects

[prisma locust]

i see i see, the teacher didnt say anything so i think it's fine, thank you very much!! :)))
