Answer: D) 10 sin (πx) - 5

<u>Step-by-step explanation:</u>

The range (maximum - minimum) is 5 - (-15) = 20

The amplitude (A) is range (20) ÷ 2 = 10

The vertical shift (D) is maximum (5) - amplitude (10) = -5

Of the given options, only A & D are candidates. Now we need to decide if it is a cos graph (A) or a sin graph (D). If we shift the graph up 5 units (to eliminate the vertical shift) , the graph would pass through the origin. Thus it is a sin graph and the answer must be option D.

Answer:

Step-by-step explanation:

$\sf Formula: \\\\\sin 2 \theta = 2 \sin \theta \cos \theta$

$\text {\sf \Large Solution :}$

$\cos 2 \theta +\dfrac{\sin \theta\cdot \cos \theta }{\sin 2 \theta } = \\\\\ \cos 2 \theta +\dfrac{\sin \theta\cdot \cos \theta}{2\sin \theta\cdot \cos \theta} =\boxed{\cos 2 \theta +\dfrac{1}{2} }$
