cos x + x2 + K
cos x 2x + K
-cos x + x2 + K
-cos x + 2x + K
Correct answer is D
∫(sin χ + 2)dχ = (∫sin χ + ∫2)dx
= -cos χ + 2χ + K
3(2x+1)2
6(2x+1)
3(2x+1)
6(2x+1)2
Correct answer is D
y = (2x + 1)3
dy/dx = 3(2x + 1)3-1 x 2
= 3(2x + 1)2 x 2
= 6(2x + 1)2
What is the locus of point that is equidistant from points P(1,3) and Q(3,5)?
y = -χ + 6
y = -χ - 6
y = χ + 6
y = χ - 6
Correct answer is A

100/7
80/7
110/7
90/7
Correct answer is C
| Area of a sector = | θ | x πr2 |
| 360 |
= 50/360 x 22/7 x 36/1
= 110/7
