  1. Q1. The value of sin 30 is:

    • A.1/sqrt2
    • B.1/2
    • C.1
    • D.sqrt3/2

    Answer: B. 1/2

    Given 30, asked for the unknown. By sin30 = 1/2. sin30 = 1/2. So option B) 1/2. Others fail: option A) '1/sqrt2' is incorrect: That is sin45; option C) '1' doesn't hold - sin90 = 1.

  2. Q2. The value of tan 90 is:

    • A.undefined
    • B.1
    • C.0
    • D.infinity is loosely said but it is undefined

    Answer: A. undefined

  3. Q3. The value of sin 30 is (NCERT):

    • A.1/sqrt2
    • B.1/2
    • C.1
    • D.sqrt3/2

    Answer: B. 1/2
