Differentiate the following functions with respect to x :
esin x + (tan x)x
let y = esin x + (tan x)x
⇒ y = a + b
where a= esin x ; b = (tan x)x
a= esin x
Taking log both the sides:
⇒ log a= log esin x
⇒ log a= sin x log e
{log xa = alog x}
⇒ log a= sin x {log e =1}
Differentiating with respect to x:
Put the value of a = esin x
b = (tan x)x
Taking log both the sides:
⇒ log b= log (tan x)x
⇒ log b= x log (tan x)
{log xa = alog x}
Differentiating with respect to x:
Put the value of b = (tan x)x :
