Question

find dy/dx , if y= e^xtanx

Answer 1

xtanx e^xtanx-1???

Answer 2

do you know product rule in differentiation ?

Answer 3

is it needed?

Answer 4

yes

Answer 5

Chain rule and product rule

Answer 6

i am assuming the question is
\(y= e^x \tan x\)

Answer 7

Yeah. I saw it a different way

Answer 8

if it is
\(e^{x \tan x}\)
then yes, bot chain and product rul are required!

Answer 9

seems to be like: \[y=e ^{xtanx}\]

Answer 10

So how would you do that?

Answer 11

f(g(x))= f'(x)*g(x)*g'(x)

Answer 12

that's the chain rule

Answer 13

Yeah...
