Assignment 16: Net of sphere

Introduction
This figure is sphere. A sphere is a geometrical object in three-dimensional space that is the surface of a ball.
Objectives
To observe net of sphere
User Guideline
Dear students choose slider and drag them ,move on left and right and observe net/area of sphere in this figure.
Question
Draw net of sphere where0[math]\le[/math]t[math]\le[/math]2 and1[math]\le[/math]R[math]\le[/math]3 by using GGb applet with the help of construction protocal.
Construction protocal
1.Firstly we open GGB applet[br]2. Then we choose slider tool[br]3. first slider where 0[math]\le[/math]t[math]\le[/math]2 and next slider 1[math]\le[/math]R[math]\le[/math]5[br]4. then using inputbar we write those formula[br]***Surface((t (-R) + (1 - t) R sin(-u π / 4)) cos(v), (t (-R) + (1 - t) R sin(-u π / 4)) sin(v), t sin((u / 16 R - R) / 2 π) + (1 - t) (-R cos(-u π / 4)), u, 0, 4, v, 0, 2π)[br]***Surface((t - 1) (-R) + (2 - t) R cos(-u), (t - 1) (u R - π R) + (2 - t) R sin(-u), sin((v / 16 R - R) / 2 π), u, 0, 2π, v, 0, 4) [br]5.and colour as your choice
