Question

Find derivative of cos(xy)=xy. Please show all steps

Answer 1

Is this partial derivatives?

Answer 2

Implicit relations

Answer 3

What calculus lvl though? 1 or 3?

Answer 4

Level 1. This is ap calculus ab

Answer 5

Oh sorry i mean i remember how to do it in calc 3 but not calc one

Answer 6

Oh I see. But how'd uoi like maybe solve it still though with calc 3? Wouldn't they be like the same way of solving maybe?

Answer 7

Oh I see. But how'd uoi like maybe solve it still though with calc 3? Wouldn't they be like the same way of solving maybe?

Answer 8

not quite since i would use partial derivatives to solve it

Answer 9

and i guess in a sense i could try to explain how to do it to you right now since its a little simple

Answer 10

But all it just is, is taking the partial derivative of x while keeping y constant, and then taking the partial derivative of y while keeping x constant

Answer 11

and when i say constant i mean making certain variable a constant, like a constant number

Answer 12

like 1 or 2 or 85748457 for that matter since we know that the derivative of a constant is always zero

Answer 13

Alright

Answer 14

Hey man can you help me with some other problems also?

Answer 15

I can try but its been awhile since i have done calc 1

Answer 16

Alright. Find derivative of y=tan^-1(x/2)

Answer 17

is this implicit defferentiation again?

Answer 18

or did you just want me to find the derivative of the tan inverse part?

Answer 19

No. Just regular derivative

Answer 20

alright well we know right from the bat that this is going to have to use the chain rule at the beginning

Answer 21

Since we need to take the derivative of the inside * the derivative of the outside

Answer 22

Alright
