Question

Given that `"dy"/"dx"` = yex and x = 0, y = e. Find the value of y when x = 1.

Sum

Solution

`"dy"/"dx"` = yex 

⇒ `int "dy"/y = int "e"^x  "d"x`

⇒ logy = ex + c

Substituting x = 0 and y = e

We get loge = e0+ c

i.e., c = 0  ....(∵ loge = 1)

Therefore, log y = ex.

Now, substituting x = 1 in the above

We get log y = e

⇒ y = ex.
