```				   f(x)=x^5+2x^3+2x  how to find out inverse of f(x)?
```

```										Dear barnita,
Finding the inverse of a function is quite easy.
f(x)=x^5+2x^3+2x
y=x^5+2x^3+2x
y/x=x^4+2x^2+2
x=y/(x^4+2x^2+2)
Hence the inverse is: x/(y^4+2y^2+2)

We are all  IITians and here to help you in your IIT  JEE preparation.  All the best.

Question: If xe^(xy) – y = sin^2x, then find dy/dx at x=0.

Given eqn. xe^(xy) – y = sin^2x, Differentiate y w.r.t. x as: (1)e^(xy) + xe^(xy)*[1.y + xdy/dx] – dy/dx = sin2x collect dy/dx, put x = 0: dy/dx = 1 is the answer.

xe^xy – y = sin^2x ∴ y = xe^xy – sin^2x Differention both sides w.r.t x: dy/dx = (1).(e^xy) + (x).(ye^xy) – 2.sinx.cosx ∴ dy/dx = e^xy + xy.e^xy – 2.sinx.cosx NOTE: Differentiate xe^xy by...

Prove that, If y = Sin -1 x, x ∈ (–1, 1) then dy/dx =1/√(1-x 2)

y = Sin -1 x ⇒ x = sin y dy/dx=cosy dy/dx=(dx/dy) -1 =1/cosy=1/ √(1-sin 2 y) =1/√(1-x 2 )

If sin a + sin b = 2 , then find the value of cos a + cos b

We know , and . Here, sina + sinb = 2 It is only possible when sina = sinb = 1. => a = b = π/2 So the value of cosa + cosb = cos(π/2) + cos (π/2) = 0. THANKS
