A bungee jumper plummets from a high bridge to the river below and then bounces back over and over again. At time t seconds after her jump, her height H (in meters) above the river is given by H(t)=100+75 \cos \left(\frac{\pi}{4} t\right)

(i)Find her height at the time between 0 to 12 seconds, using an appropriate standard engineering software such as MATLAB, CAS calculator, programmable calculator, Excel software.(ii)By using an appropriate standard engineering software such as MATLAB, CAS calculator,programmable calculator, Excel software, sketch the height versus time graph between 0 to 12seconds
