Question

Science has progressed so rapidly that we now have hundreds of labour-saving devices at home and at work. Robots are machines that look like humans and can act intelligently. Would you like to own a robot? Write a short account (200-250 words)about robots in general and a particular robot that you would like to own.​

Answer 1

⇢Question:-

• sin²5 + sin²10 + sin²15 + ••• + sin²85° + sin²(90°) =?

⚘Answer:-

• $\large\displaystyle \red{ { \rm{{\lim_{n \to \infty } {e}^{ - n} \sum_{ \mathbb{k = 0}}^{n} \frac{ {n}^{ \mathbb{k}} }{ \mathbb{k!}} }}}}$

⚘Explanation:-

• ㅤㅤㅤ⇢ sin θ = cos (90° – θ)
• ㅤㅤㅤ⇢ sin (90° – θ) = cos θ
• ㅤㅤㅤㅤ∴ sin 85° = sin (90° – 5°) = cos 5°

ㅤㅤㅤㅤ∴ (sin² 5° + sin² 85°) + (sin² 10° + sin² 80°) + ••• ㅤㅤㅤㅤㅤto 8 terms + sin² 45° + sin² 90°

ㅤㅤㅤㅤ⚘⇢ So, your answer was 9×1/2

Answer 2

Answer:

India has also come up with specialised programmes in robotics field in IITs and other universities. Also, it has moved beyond the traditional areas and entered newer domains of education, rehabilitation, entertainment etc. Robotics has helped handicapped people by replacing their (damaged) limbs with artificial parts that can duplicate the natural movements.

Like a coin has two sides, robotics too has a flip side to it. The biggest barrier in the development of robots has been the high costs of its hardware such as sensors, motors etc. The customisation and updation is also an added problem.

With new advancements taking place each passing day, new product introduction is a problem for the existing users. Robots cut down labour, thereby reducing the opportunities of employment for many. In many developed countries, scientists are making robotic military force that can prove dangerous to others. As the power and capacity of computers continues to expand, revolution is being created in the field of robotics. Imagination is coupled with technology. It would not be wrong to say that in near future there will be a time when robots will become smarter than the human race.
