उत्तर

x = e3t 

Differentiating both sides w.r.t. t, we get

`"dx"/"dt" = "e"^"3t" * (3) = 3 "e"^"3t"`  

y = `"e"^(4"t" + 5)`

Differentiating both sides w.r.t. t, we get

`"dy"/"dt" = "e"^((4"t" + 5)) xx 4`

`= 4 * "e"^((4"t" + 5))`

∴ `"dy"/"dx" = (("dy"/"dt"))/(("dx"/"dt"))`

= `(4 * "e"^(4"t" + 5))/(3* "e"^(3"t"))`

`= 4/3 e^(4"t" + 5 - 3"t")`

`= 4/3 "e"^("t" + 5)`

If x = `(4"t")/(1 + "t"^2)`, y = `3((1 - "t"^2)/(1 + "t"^2))`, then show that `("d"y)/("d"x) = (-9x)/(4y)` 


Find `("d"y)/("d"x)`, if x = em, y = `"e"^(sqrt("m"))`

Solution: Given, x = em and y = `"e"^(sqrt("m"))`

Now, y = `"e"^(sqrt("m"))`

Diff.w.r.to m,

`("d"y)/"dm" = "e"^(sqrt("m"))("d"square)/"dm"`

∴ `("d"y)/"dm" = "e"^(sqrt("m"))*1/(2sqrt("m"))`    .....(i)

Now, x = em

Diff.w.r.to m,

`("d"x)/"dm" = square`    .....(ii)

Now, `("d"y)/("d"x) = (("d"y)/("d"m))/square`

∴ `("d"y)/("d"x) = (("e"sqrt("m"))/square)/("e"^"m")`

∴  `("d"y)/("d"x) = ("e"^(sqrt("m")))/(2sqrt("m")*"e"^("m")`
