eight A communication sign is given by the operate y=sin?t/t
The duty is to:
Derive an equation for dy/dt utilizing the Quotient Rule.
9 An organization is required to fence off a sq./rectangular space round a robotic arm to adjust to well being and security regulation. They've 750m of fencing obtainable.
The duty is to:
Discover the utmost sq./rectangular space they'll fence off?
10 You propose to make a easy, open topped field from a chunk of sheet metallic by chopping a sq. – of equal measurement – from every nook and folding up the edges as proven within the diagram: If l=200mm and w=150mm calculate:
The worth of x which is able to give the utmost quantity
The utmost quantity of the field
Remark of the worth obtained partially b.
