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

The correct answer is letter C.
Sea and land breezes over a large region that change direction with the season are called monsoons. These are seasonal changes in the direction of winds in a particular region which causes its wet and dry seasons.These monsoons are often associated with the Indian Ocean and tend to move from cold to warm regions in a particular region.

Generally, the more allowances the employee claims on a Form W-4, the lower the withholding tax. Withholding tax applies to income earned through wages, pensions, bonuses, commissions, and gambling winnings. Dividends and capital gains, for example, are not subject to withholding tax
