These satellites make it possible for us to talk on the phone, watch television, predict the weather, map the various surfaces of the earth and learn more about the world in which we live.
How does a satellite get started? It is typically launched into space by means of a rocket. After ascending into the thinner air layers above the earth, the satellite is released from the rocket. For a successful satellite launch, a rocket's speed is carefully calculated and controlled. Every object in space is pushed towards the Earth's centre by gravity. The inertia of motion will propel the object into space if it has its own velocity of motion. When the orbital velocity is exactly right, these two opposing forces are balanced, causing the satellite to (3) _____ towards the earth while still hovering over its surface. earth in a 24-hour period; It doesn't change when compared to a point on the surface of the earth. These orbits are typically used by satellites for communication and weather. The camera on the weather satellites takes pictures and sends them back to Earth.

Question : If $\frac{\sin x-\cos x}{\sin x+\cos x}=\frac{2}{5}$, then the value of $\frac{1+\cot ^2 x}{1-\cot ^2 x}$ is:

Option 1: 2.25

Option 2: 1.45

Option 3: 3.75

Option 4: 5.25

Team Careers360 26th Jan, 2024

Correct Answer: 1.45


Solution : $\frac{\sin x-\cos x}{\sin x+\cos x}=\frac{2}{5}$
Dividing both the numerator and denominator by $\cos x$
⇒ $\frac{1-\cot x}{1+\cot x}=\frac{2}{5}$
⇒ $5-5\cot x=2+2\cot x$
⇒ $\cot x=\frac{3}{7}$
So, $\frac{1+\cot ^2 x}{1-\cot ^2 x}$=$\frac{1+(\frac{3}7) ^2}{1-(\frac{3}7)^2 }=\frac{58}{40} = 1.45$
Hence, the correct answer is 1.45.
