The first thing you have to realize is that
tangent is the
slope of a curve on a given point. You can solve for the slope by finding the derivative of the given function. So:
Next use
product rule (I recommend watching videos if you're confused):
![= [sin(x)] + [x*cos(x)]](https://tex.z-dn.net/?f=%3D%20%5Bsin%28x%29%5D%20%2B%20%5Bx%2Acos%28x%29%5D)
Next substitute you x-value (π/2) into your derivative:
![= [sin( \frac{ \pi}{2} )] +[ \frac{\pi}{2}*cos( \frac{\pi}{2})]](https://tex.z-dn.net/?f=%3D%20%5Bsin%28%20%20%5Cfrac%7B%20%5Cpi%7D%7B2%7D%20%29%5D%20%2B%5B%20%5Cfrac%7B%5Cpi%7D%7B2%7D%2Acos%28%20%5Cfrac%7B%5Cpi%7D%7B2%7D%29%5D%20%20)
So our slope at π/2 is 1. Next we use our slope-form and substitute our given value and solve for y-intercept (algebra-stuff)
So we get our equation:
So our answer is E

Answer: c) Researchers think that stresses created by humans are the reason behind increasing numbers of elephant attacks.
Explanation:
The aforementioned article by National Geographic shows that the higher number of elephant attacks on humans are as a result of human activities that are placing stress on elephants.
Humans are increasing in population and as a result need more land for farming. This is resulting in a shrinking habitat for elephants who then encroach on human farms and are killed for it which leads to some elephants having Post Traumatic Stress Disorder and killing other humans which then continues the cycle.
<span>Spain's conquest of central Mexico and the Andes made Spain the wealthiest and most powerful nation because of the abundance of gold and silver which it gained. This large amount of gold and silver it was able to obtain was sent to its national treasuries allowing it to become a threat to any other European competition.</span>

Answer:
1. The main argument made about Indian Ocean ports is that they serve people from different parts of the world.
2. Their accommodation of different religions
3. Diffusion of religion is one similarity between the regions described in the passage and the Silk Roads.
Explanation:
From the passage, the narrator goes on to show that the Indian ports of Hormuz and Calicut served people from different Asian and Arabic countries around the globe. When he arrived at Calicut, he noted the cohabitation of Muslims and Hindus. Their tolerance of each other must have facilitated trade.
Just like the Silk Roads which served merchants from different parts of the world, thus leading to a diffusion of many aspects of culture, the Indian ports also provided the same advantage.
