Question

f(x,y)=e^x.sin(y)

how to get the value of x, if the only information we have is f(x,y)=0 ?

Answer 1

well, we should know that whenever you multiply by 0 you get zero right?

Answer 2

well if f(x,y) = 0

then set the equation to zero

0 = e^(x.sin(y))

Answer 3

and solve for x and y

Answer 4

e^n is never zero

Answer 5

yeah, but e^x cant be zero

Answer 6

is siny in te exponent?

Answer 7

nope sin(y) is not a component, sorry making u guys confuse

Answer 8

sin(0) = 0

thus we can deduce that y = 0

so we have

0 = e^(x)sin(0)

Answer 9

then x is any value; as long as sin(y) = 0

Answer 10

x can be any real number :\

Answer 11

stole my thunder amistre64

Answer 12

*kapow* lol

Answer 13

although to be fair I knew the answer about a minute after thinking about it I was just explaining it

Answer 14

the answer is that x is any value or the value of x is indeterminable based on the information provided

Answer 15

oh yeah? i knew it three days ago and was just waiting for the opportunity to give it ;)

Answer 16

damn I can't compete with that

Answer 17

Yeah i was asked to find the value of x in exam. I wonder was that a mistake ?

Answer 18

x = any real number

Answer 19

x
=
\[\mathbb{R}\]

Answer 20

you could also say a value cannot be specified based on the information provided

Answer 21

both are right answers

Answer 22

Ok thanks guys =D
