A phase shift is defined as the a<span>mount of x by which sinusoid is shifted to the left or right.
And yes, </span><span>every sine function be expressed as a phase shifted cosine function:
</span>
sin(t)=cos(90-t)
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
<span>You can remember by the acronym: PEMDAS which stands for p<span>arenthesis, exponents, multiply, divide, add, subtract
So you start with anything in parenthesis

Answer:
Step-by-step explanation:
Given two non zero vectors, .
Let the angle between the two vectors =
Given that:
Let us have a look at the formula for magnitude of addition of two vectors:
Where is the angle between the two vectors.
formula for magnitude of subtraction of two vectors:
As per the given condition:
Squaring both sides:
So, the angle between the two vectors is:
$225 = 15h + 75
150 = 15h
h = 10
The answer is 10. Hope this helps :).
