### Question 1. Find Solution:

Let considered x – 1 = t,

so that dx = dt

Thus, ### Question 2. Evaluate Solution:

Let I = ### Question 3. Evaluate Solution:

I = Hence, ### Question 4. Evaluate Solution:

Let I = Therefore, I = ### Question 5. Solution:

I = Let us considered sinx = t

So, on differentiating, we get

cosx dx = dt

I = Therefore, I = ### Question 6. Evaluate Solution:

I = Let us considered ex = t

So, on differentiating, we get

exdx = dt

Therefore, I = Hence, I = ### Question 7. Evaluate Solution:

I = Therefore, I = ### Question 8. Evaluate Solution:

Let us assume I = Therefore, I = ### Question 9. Evaluate Solution:

Let us assume I = Therefore, I = ### Question 10. Evaluate Solution:

Let us assume I = Therefore, I = ### Question 11. Evaluate Solution:

Let us assume I = Therefore, I = ### Question 12. Evaluate Solution:

Let us assume x2 = t

On differentiating we get

2x dx = dt

Therefore, I = Hence, I = ### Question 13. Evaluate Solution:

I = Let us considered x3 = t

So, on differentiating, we get

3x2dx = dt

Therefore, I = Hence, I = ### Question 14. Evaluate Solution:

I = Let us considered logx = t

So, on differentiating, we get

1/x dx = dt

Therefore, I = Hence, I = ### Question 15. Evaluate Solution:

I = Therefore, I = ### Question 16. Evaluate Solution:

Let I = I = I think you got complete solutions for this chapter. If You have any queries regarding this chapter, please comment in the below section our subject teacher will answer you. We tried our best to give complete solutions so you got good marks in your exam.
