Respuesta :
[tex]\bf A=cos(\theta )\qquad \qquad B=sin(2\theta )\\\\
-------------------------------\\\\
B=sin(2\theta )\implies B=2sin(\theta )\stackrel{A}{cos(\theta )}\implies B=2sin(\theta )A
\\\\\\
\textit{or also }\qquad \cfrac{B}{2sin(\theta )}=A[/tex]
The relationship between the functions A and B will be B = 2A sin θ.
What is a function?
A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function is given below.
A = cos θ
B = sin 2θ
Then the relationship between A and B will be given as,
We know that the formula of sin 2x = 2 · sin x · cos x
Then the equation will be
B = 2 · sin θ · cos θ
Substitute the cos θ = A, then the equation will be
B = 2 · sin θ · A
B = 2A sin θ
The relationship between A and B will be B = 2A sin θ.
