Question

find both partial derivative
z=sin(x+2y)

Answer 1

wrt?

Answer 2

\[z _{x}=\cos (x+2y)\]
\[z _{y}=2\cos (x+2y)\]

Answer 3

how?

Answer 4

wait. there's no symbol for the partial derivative here..

Answer 5

its ok if there is no symbol of partial

Answer 6

i already know how to solve this :)

Answer 12

wrt to what?

Answer 13

partial derivative

Answer 14

respect to x .. y ..

Answer 15

partial deriv wrt x is sinh(xy^2)
partial wrt to y is (2y)sinh(xy^2)

Answer 16

oops. partial wrt y = 2xy sinh(xy^2)

Answer 17

not -sin?

Answer 18

nope. there's a slight difference for hyperbolic functions :)
