Answer: to find the mean add up all the scores and then divide it by the number of scores that are there and to find the mode order the numbers lowest to highest and see which number appears the most
Given data
<span>sin (x+pi/2)=cos x
</span>now using sin law
sin(a+b)=sin(a)cos(b)+cos(a)sin(b)
now using above values
sin(pi/2+x)=sin(pi/2)cos(x)+cos(pi/2)sin(x)
as we know that
sin(pi/2)=1
cos(pi/2)=0
now putting these values
sin(pi/2+x)=1*cosx+0*1
sin(pi/2+x)=cosx
hence proved that
<span>sin (x+pi/2)=cos x</span>
Answer:
The lower left image is best
Step-by-step explanation:
Sine 0 or -π are both zero, but increasing x would normally have the line moving above the neutral line. Subtracting π from the x value inverts the sine wave so the line moves first below the neutral line as x increases.
Subtracting 2 from all sine results shifts the neutral line down 2 units.
