Question

Use the rules of differentiation to find the derivative of the function y=.7x=3cosx

Answer 1

check your statement.

Answer 2

what do you mean?

Answer 3

y=.7x=3cos x

Answer 4

is it .7x=3cos x or .7x-3cosx

Answer 5

it is y = .7x = 3cosx

Answer 6

to me it is not correct.
can you tell me the answer so that i can check if there is any change in statement?

Answer 7

the answer isnt given

Answer 8

can you try a different one and i can figure out the process?

Answer 9

\[\frac{ dy }{ dx }=.7=-3 \sin x\]

Answer 10

how would i do it for y= \[3\div \sqrt[4]{x}-7sinx\]

Answer 11

\[y=\frac{ 3 }{ x ^{\frac{ 1 }{ 4 }} }-7 \sin x=3x ^{\frac{ -1 }{ 4 }}-7 \sin x\]
\[\frac{ d }{ dx }\left( x^n \right)=nx ^{n-1}\]
\[\frac{ d }{ dx }\sin x=\cos x\]

Answer 12

\[\frac{ dy }{ dx }=3*\left( -\frac{ 1 }{ 4 } \right)x ^{\frac{ -1 }{ 4 }-1}-7\cos x\]
?
