```				   ∫2x-[x]  .dx
limits from 0 to [x]
```

```
To solve this divide the integrals into o to 1 ,1 1to 2 ..... upto [x]-1 to [x]

so you get integrations of 2^(x-0) from 0 to 1 +2^(x-1) from 1 to 2 .... upto 2^(x-[x]+1) from [x-1]to [x]

each integral evaluates to 1/ln2 so we have [x] terms in our integral sum expression ..

therefore you get  ans=[x]/ln2

∫(1/sinx)dx

1/sinx =cosec x or integration of 1/x = ln |x|+c where c is arbitari constant so by using this formula integration of i/sinx is ln |sinx +c|

If I= integral tan(tan^-1 (x)) than find the value of I. I=?

tan(tan^-1 (x)) = x So I = integral x dx so I = x^2 /2 now find I.I Thanks

Tangents from the points T to the ellipse x2-y2 equal 1 cut off a length equal to the minor axis from the tangent at (a,0). Prove that T lies on a parabola

I apologize for my mistake.it should be a standard form ellipse, that is x^2/a^2 + y^2/b^2 = 1. Hope you can give me required detailed solution for this problem

 JOEL JOHNSON 2 months ago

Dear Joel, First of all The eqn. x2-y2 equal 1 doesn't makes sense. It's not an ellipse. Check the required eqn plz.

how to solve inequality

Look for the range of values of input variable, which will satisfy the inequality. Thanks

 Vijay Mukati one year ago

No any trick as such. Use your logic to solve them. Thanks.

 Vijay Mukati one year ago

Most of them are based on AM-GM. You can also check the range of functions on both sides and then solve.
