BCA TU Mathematics I Question Paper 2020
Today we are going to see and discuss the question paper of Mathematics I of first semester year 2020. We have embedded the PDF of the question paper as well and provided a download link at the end of this article. Mathematics subject is favorite for many and boring foe many. Whether its boring or favorite subject for you if you want to get good scores in the exam then you must practice old question.
For the same reason we are providing you the question paper of BCA TU First Semester Mathematics I belwo:
- The first question of the group B was asked from the SETS chapter. The question asked to find how many people liked all the drinks and how many liked only one drink. If you have ever practiced Sets exercises you might have practiced this question so I suppose this question is not much tough.The question was like this:
- 2) Out f 500 people 285 like tea, 195 like coffee, 115 like lemon juice, 45 like tea and coffee, 70 like tea and juice, 50 like juice and coffee. If 50 do not like any drinks: i) How many people like all drinks ? ii) How many like only one drinks?
- The second question was asked to prove x sq. + y sq. = 1. This question was from Real and Complex Number Chapter. If you know to solve imaginary number i related questions then its super easy for you.
- Third question was " If H is the Haramonic mean between a and b then prove that: 1/H-a + 1/ H-b = 1/a + 1/b" I think you already know this question is from Sequence and Series Chapter. Although this question is not much tough, its hard than first two question.
- Fourth question asked to define singular and non singular matrix and to find the inverse of a 3X3 matrix.
- Fifth Question was from the Circle chapter. Question was asked to find the focus, vertex, equation of the axis, equation of the directrix and length of the latus rectumm of ellipse.
- Sixth: If theta is the angle between two unit vectors and b then prove 1/2|vector a - vector b| = sin (theta/2)
- Seventh: How many members of at least three different digits can be formed by using digits 1,2 ,3 ,4 5,6 ?
And from the group C following questions were asked:
- 9. Prove by vector method: cos(A+B) = cosA.cosB- sinA.sinB
- 10. Find the equation of circle passing through points (1,2) (3,1) and (-3, -1)
