Sum of 1st cube no N th triangle no
Answer:
Step-by-step explanation:
Given the equation of velocity w.r.to time 't':
<em>Formula for Displacement</em>:
So, if we find integral of velocity w.r.to time, we will get displacement.
Here, C is constant (because it is indefinite integral)
<u>Formula for integration used:</u>
<u></u><u></u>
<u></u>
Now, it is given that s = 0, when t = 0.
Putting the values in equation (1):
So, the equation for displacement becomes:
Answer: A) none of the equations are identities
==========================================
Part 1
Plug in theta = 0
sin(theta+pi/2) - cos(theta+pi/6) = 2*cos(theta) - sin(theta)
sin(0+pi/2) - cos(0+pi/6) = 2*cos(0) - sin(0)
1 - sqrt(3)/2 = 2*1 - 0
0.13 = 2
which is a false equation
So we do not have an identity in equation 1.
-------------------------------------------
Part 2
Plug in theta = 0
sin(theta+pi/6) + cos(theta+pi/3) = (sqrt(2)/3)*sin(theta) + 2*cos(theta)
sin(0+pi/6) + cos(0+pi/3) = (sqrt(2)/3)*sin(0) + 2*cos(0)
1/2 + 1/2 = 0 + 2
1 = 2
which is also false
This is not an identity either.
