Answer 1

@jazy can u help? @mathsmind ?

Answer 2

by definition or the normal way?

Answer 3

f'(x) = 3x^2-2

Answer 4

by solving it how would i do it?

Answer 5

normal way you can say

Answer 6

nx^(n-1)

Answer 7

the answer is up there

Answer 8

f'(x) = 3x^2-2

Answer 9

ok?

Answer 10

Is this clear?

Answer 11

Answer 12

you need to know this by heart

Answer 13

there is no -2

Answer 14

ok

Answer 15

we use the normal method nx^n-1

Answer 16

for example x^10, diff, 10x^(10-1)
