Section A |
|
|
1) If A= {0, π/6, π/4,π/3,π/2) and f: A→B is a surjection defined by f(x)=cosx, then find B |
B={1,3/2,1/2,1/2,0} |
|
2) Find the domain of real valued function f(x)= √x2-25 |
(−∞,−5]∪[5,∞) |
|
3) Find the additive inverse of A, where A=[i 0 1 |
(-i 0 -1 |
|
4) Find the unit vector in the direction of vector a=2i+3j+k |
(2/√14)i + (3/√14)j + (1/√14)k |
|
5) Find the vector equation of the line passing through the point 2i+3i and parallel to the vector 4i-2j+3k |
r=5i+λ(4i−2j+3k) |
|
6) If |p|=2,|q|=3 and(p,q)=n/6, then find |pxq|2 |
36 − n²/36 |
|
7) Find the value of sin 330. cos 120+cos 210. sin 300 |
1 |
|
8) Find the range of 7 cosx-24 sinx+5 |
Range = [−20 , 30] |
|
9) For any x€R, prove that cosh4x-sinh4x=cosh(2x) |
cosh⁴x − sinh⁴x = cosh(2x) |
|
10) If A (o 2 1 |
x=1 |
|
Section B |
|
|
11) If [x-1 2 5-y = [1 2 3 |
x=2,y=2,z=5,a=5 |
|
12) If A,B,C, and D be four points with position vectors a+2b, 2a-b, a, and 3a+b, respectively, express the vectors AC, DA, BA, and BC in terms of a and b |
AC = −2b |
|
13) If a+b+c=0, then prove that axb=bxc=cxa |
a+b=−c. Take cross product with a: a×a+a×b=−a×c⇒a×b=c×a. Repeat for b. Hence Proved. |
|
14) If A+b=π4, then prove that (1+tan) (1+tanB)=2 |
tan(A+B)=tan(π/4)=1. Use formula 1−tanAtanBtanA+tanB=1. Cross multiply and add 1 to both sides. Hence proved. |
|
15) Find the general solution of the equation sin2θ-cosθ=1/4 |
θ ≈ 0.73 + 2nπ (n ∈ ℤ) |
|
16) Prove that tan-1 3/4+tan-1 3/5-tan-1 8/19= π/4 |
Use tan−1x+tan−1y formula twice. First: tan−11−1/101/2+1/5=tan−197. Then: tan−11−7/727/9+1/8=tan−1(1). Hence, proved. |
|
17) In ΔABC, if a=13, b=14,c=15, then find r1 |
r=4 |
