Tips Answers for CA
Didnt answer 2c and only give the formula for 5
If u see any mistakes, plz inform me.
1. RGB-
(R,G,B)
CMY-
Magenta = (RGB white)-(RGB magenta) = (1,1,1) – (1,0,1) = (0,1,0)
2.
a. Vector A->C = C-A= (4,1,2) – (3,3,2) = (1,-2,0)
Vector A->B = B-A= (2,2,1) – (3,3,2) = (-1,-1,-1)
Vector B->C = C-B= (4,1,2) – (2,2,1) = (2,-1,1)
b. Dot product A->B . B->C = (-1,-1,-1) . (2,-1,1) = (1st * 1st)+ (2nd *2nd)+(3rd * 3rd)
=(-1*2)+(-1*-1)+(-1*1)=-2
3. First Object
glBegin (GL_LINE_LOOP);
glvertex2i (200,60);
glvertex2i (240,150);
glvertex2i (280,60);
glvertex2i (190,120);
glvertex2i (290,120);
glEnd();
Second Object
glBegin (GL_LINE_STRIP);
glvertex2i (200,60);
glvertex2i (280,60);
glvertex2i (240,150);
glEnd();
glBegin (GL_LINE_STRIP);
glvertex2i (290,120);
glvertex2i (190,120);
glvertex2i (240,30);
glEnd();
4. Transform Rotate Scale
|1 0 tx| |cos& -sin& 0 | |sx 0 0 |
|0 1 ty| | sin& cos& 0 | |0 sy 0 |
|0 0 1 | | 0 0 1 | |0 0 1 |
The matrixes must be written from right to left. Instead of [S] [R] [T], the order of the question.
We have [T][R][S] (Remember This!!)
Transform Rotate Scale
|1 0 2 | | 0 -1 0 | |3 0 0 |
|0 1 2 | | 1 0 0 | |0 4 0 |
|0 0 1 | | 0 0 1 | |0 0 1 |
Then add them one by one.
[T]+[R]
[T] 1st row by [R] 1st column = (1*0)+(0*1)+(2*0)=0
[T] 1st row by [R] 2nd column = (1*-1)+(0*0)+(2*0)=-1
[T] 1st row by [R] 3rd column = (1*0)+(0*0)+(2*1)=2
[T] 2nd row by [R] 1st column = (0*0)+(1*0)+(2*1)=2
[T] 2nd row by [R] 2nd column = (0*-1)+(1*0)+(2*0)=0
[T] 2nd row by [R] 3rd column = (0*0)+(1*0)+(2*1)=2
[T] 3rd row by [R] 1st column = (0*0)+(0*0)+(1*1)=1
[T] 3rd row by [R] 2nd column = (0*-1)+(0*0)+(1*0)=0
[T] 3rd row by [R] 3rd column = (0*0)+(0*0)+(1*1)=1
So[TR] =|0 -1 2|
|2 0 2|
|1 0 2|
Then repeat the steps for [TR] + [S]
5. Xb = m∑i=0 mCi ui (i-u)m-I X
Yb = m∑i=0 mCi ui (i-u)m-I Y
m= number of point given -1
C= Combination (We did this B4)
Software Testing Tips
2. draw cause effect graph
3. Identify THREE actions involved during form testing
4. Briefly describe end-to-end transaction testing
5. What is a legacy system? define
6. Describe FOUR attributes of quality test case
7. CFG, Cyclomatic complexity value...

Software Project Management Exam Tips
- NPV, ROI, payback
Topics
- WBS, Weighted scoring model
- For WBS must at least three levels
- Check example of building a house
- EVM
- Textbook pp 285-291
- Tutorial 12 (Chapter7revised) page1 q1
- AOA
- Tutorial 8 page 2
- Text book pp 223-224, 255(q2)
- Project time management
- Critical path is the longest path
EVM Formulas
- EV = PV to date * RP
- CV = EV - AC
- SV = EV - PV
- CPI = EV/AC
- SPI = EV/PV
- EAC = BAC/CPI
- ETC= OTE/SPI
EV - Earned Value
PV - Planned Value
RP - Rate of Performance
CV- Cost Variance
AC- Actual cost
SV- Schedule Variance
CPI- Cost Performance Index
SPI- Schedule Performance Index
EAC- Estimate at Completion
BAC-Budget at Completion
ETC-Estimated Time to Complete
OTE-Original Time Estimate
Analyzing
Important factors in project are cost and time
- CV represents the cost performance
- SV represents the time performance
- If they are positive, they are ahead of schedule/under budget if negative they are behind schedule/ over budget
- CPI represents the cost performance as an index/performance. It verifies the CV
- SPI represents the time performance as an index/performance. It verifies the SV
- Over 100% is good ( they are ahead of schedule/under budget ) 100% is neutral and below 100% is bad (behind schedule/ over budget)
- If EAC is higher than BAC then the project is performing worse than planned because the new estimate to complete the project is x more than planned.
- You get OTE from the question, where they mention how long the project was intended to take
- If ETC is higher than OTE then the project is performing worse than planned because the project is projected to take x months longer than planned.
Exam Tips for CA
2. Given 3 points ( 3, 3, 2) , (2,2,1) and (4,1,2) find the vector, dot product, cross product and plane equation.
3. Draw the 2 object below with Open GL code
4. 2D transformation
Compose a 2D transformation matrix with
- scale in x by 3 and in y by 4; (Scale(3,4))
- then rotate trough 90 degree around origin (rotate(90))
- translate trough (2, 2)
5. Bezier Curve
Given V0(0,3), V1(1,5), V2(4,0) and V3(6,2) are the control points. Find the points where the curve will pass through when U = 0.5 using bezier curve technique
6. Find vector list, edge list, normal list and face list from a 3d object.
7. Describe each below:
Pre-production, Production, Post-production
8. Express the following terms : Animatronic, stop motion animation.
9 A triangle below is to be rotated for 30 degree in anti-clock wise order. given the pivot point (black dot) at (2,3) find the composite matrix in 2D space to perform the transactin.
