[The solution will be available soon. Stay tune.] – Well guys no one willing to share the project ans with us…all of you want the answer only … I can’t help you this time because my SPM is last year… so anyone willing to share pls email to ‘email[AT]evozi[DOT]com’
Rene Descartes, a renowned French Mathematician in the 16th century, discovered the beauty of Cartesian coordinates system while lying on his back and gazing at a spider on the ceiling. Do some research and write about his discoveries.
Malaysia with its warm tropical climate is rich in flora and fauna. Beautiful gardens are found all over Malaysia. SMK Pennata decided to beautify the school compound by getting the students involved in the planting and maintenance of the greenery in the school compound as shown in Diagram 1. Each society is allocated a plot of land in various shapes and sizes to nurture throughout the year. The Mathematics Society, Englisl, Language Society and Malay Language Society are allocated the region P, Q and R respectively as shown in Diagram 1.
(a) Determine the area of region P, Q and R by using at least three different methods including the use of calculus. Ve -ify the answers obtained by using computer software. (Suggestions: GeoGebra, GSP, graphing calculator etc)
(b) Suppose there is a hcdgc along AB. The Mathematics Society wishes to fence up the remaining sides of the region P. Determine the length of fence required.
(c) If a meter of fence costs RM25.00, what is the total cost required by the Mathematics Society to fence up region P? Is it possible for the society to carry out the fencing with an allocation of RM250.00? Explain your answer.
(d) During the Mathematics Week, the society was given a single flag chain of length 9.20 meters to be used completely. The President of the society wishes to tie the flag chain continuously from A to E and then to another point along the hedge AB to create a triangular-shaped area.
(i) Make a conjecture about the number of points that the flag chain can be tied to along AB.
Support your conjecture with suitable calculations. Explain your answer.
(ii) Calculate the maximum area of the triangle obtained. Discuss.
The Mathematics society decided to build a pond in region P as shown in Diagram 2. The pond is in the shape of a sector with centre E, radius ED and a depth of 1 meter.
(a) Calculate the angle AED, in radians, by using at least two different methods.
(b) Determine the volume of water that has to be pumped in to fill up 80% of the pond.
(c) If the water is pumped into the pond at a constant rate of 0.001 m3 s-‘, calculate
(i) the i ute of change of depth of the water,
(ii) the depth of water after 10 minutes,
(iii) the minimum time taken, in minutes, before the water overflows, and
(iv) the minimum time taken, in minutes, before the water overflows, if the pond is triangular-shaped AED and has a depth of 2 meters.
Maps have been used for thousands of years to aid travelers during their journey from one place to another. Maps can also be used to estimate distance between places. In the year 2014, a recreation park will be constructed in town marked `X’ on the map of Malaysia in as shown Diagram 3. This town has the latitude of 5° 41′ N has the same longitude as the city of Malacca.
Explore and find the distance between these two places in kilometer by using,
(i) the map in Diagram 3
(ii) the formula given below:
Distance = θ x 60 nautical miles
where θ= difference in latitudes in degrees.
(a) Surf the Internet and use the Google map to locate the position of your school and two nearby hospitals/clinics. Print a copy of this Google map anc’ mark the position of these three places.
(i) Solve the triangle obtained.
(ii) Calculate the shortest distance from your school to the line joining the two hospitals/clinics.
If Internet service is not available, you can perform this task by using a detailed map of your town.
