Answer:
A is the correct answer.
Step-by-step explanation:
First we use sin(a+b)= sinacosb+sinbcosa
and cos(a+b)=cosa cosb -sinasinb
tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)
and sin(x+pi/2) = sinxcospi/2 + sinpi/2cosx =cosx,
<span>cos(x+pi/2) = cosxcospi/2- sinxsinpi/2= - sinx,
</span> because <span>cospi/2 =0, </span>and <span>sinpi/2=1
</span><span>=tan(x+pi/2)= sin(x+pi/2) / cos(x+pi/2)= cosx / -sinx = -1/tanx = -cotx
</span>from where <span>tan(x+pi/2)=-cotx</span>

The quantities that are not constant in uniform circular motion are :
1. Angular Velocity , the direction keep changing in angular velocity so it's not constant
2. Angular position, theta will keep on changing until it reach 360
3. Direction of centripetal acceleration
hope this helps
Answer:
graph 1= 3. graph 2= -3
Step-by-step explanation:
the y-intercept is where it cuts the line
therefore,
graph 1=3
graph 2=-3
